Quick answer: Same = identical, exactly alike (always with “the”: the same as). Similar = resembling but not identical (similar to). “They go to the same school” means one identical school they both attend. “The two schools are similar” means they are alike in many ways but are two different schools. For a fuller definition, see the Cambridge Dictionary entry for ‘same’.
At a Glance: Same vs Similar
Both same and similar describe how much two or more things resemble each other, but at very different levels. Same means absolutely identical — the things are one and the same, or exactly alike in every way being discussed. Similar means there are notable resemblances, but differences also exist. Getting these two words right is important both in everyday communication and in English exams.
| Word | Part of Speech | Core Meaning | Examples |
|---|---|---|---|
| same | adjective / pronoun | identical; not different in any way (always used with “the”) | We have the same teacher. / Your bag is the same as mine. |
| similar | adjective | resembling but not identical; alike in some but not all ways | Their opinions are similar. / similar to last year’s results |
Using “Same”
Same indicates complete identity — the two things being compared are one single thing, or they match each other exactly. The most important grammar rule is that same used as an adjective in this sense always requires the definite article “the” before it.
We read the same book last year.
She has the same colour eyes as her mother.
We read same book last year. (missing “the” — incorrect)
After same, the comparison is made with as (not than or like):
His phone is the same as mine.
This task is the same as the one we did last week.
His phone is the same like mine. (incorrect — use as, not like)
“Same” in Common Phrases
Several very frequent English expressions use same in ways that you should learn as fixed phrases:
- at the same time — simultaneously; or “however, on the other hand” in discourse
- in the same way — using the same method or approach
- same here (informal) — “I feel / think the same” (responding to something someone said)
- the same old story — a situation that keeps repeating in a familiar, often frustrating way
- the same goes for — “this applies equally to”: The same goes for you.
- all the same — despite what was said; nevertheless: I’d like to try, all the same.
Using “Similar”
Similar describes partial resemblance — the things have notable similarities but are not completely identical. After similar, the comparison uses to (not as):
Your results are similar to mine.
This approach is similar to what we tried last year.
Your results are similar as mine. (incorrect — use to, not as)
Similar can also be modified by degree adverbs to show how close the resemblance is:
- very similar — The two methods are very similar.
- remarkably similar — Their stories are remarkably similar.
- fairly similar — The results were fairly similar across all groups.
- somewhat similar — a formal way of saying “slightly resembling”
Similar can also take in when specifying which aspect is being compared:
The two buildings are similar in size but different in style.
The results were similar in many respects.
Forming Sentences: “Similar to” vs “The Same as”
The two key patterns to remember are:
- X is the same as Y — X and Y are identical
- X is similar to Y — X and Y resemble each other but are not identical
My idea is the same as yours. (identical idea)
My idea is similar to yours. (alike but not the same idea)
Notice that same as uses as and similar to uses to. Mixing these up is the most common error with this word pair.
Side by Side: Same vs Similar
They wear the same uniform. (identical — one uniform worn by all)
Their uniforms are similar. (alike but possibly different colours or details)
I made the same mistake as you. (exactly the same error)
I made a similar mistake. (a comparable but not identical error)
We go to the same gym. (one gym, both attend it)
Our gyms are similar. (different gyms with comparable facilities)
Common Mistakes to Avoid
Mistake 1 — “Similar as” (wrong preposition)
Similar is always followed by to, never as: “similar to mine” not “similar as mine.” This is one of the most common errors made by learners of all levels. Remember: the same as / similar to.
Mistake 2 — “Same to” (wrong preposition)
Same takes as, not to: “the same as mine” not “same to mine.” The error of writing “same to” often comes from direct translation from other languages. Always use as after same when making a comparison.
Mistake 3 — Missing “the” before “same”
In English, same used as a predicative adjective or a modifier meaning “identical” always requires the definite article “the”: “they are the same” not “they are same.” Without “the,” the sentence sounds incomplete or ungrammatical to native speakers.

Frequently Asked Questions
What is the difference between same and similar?
Same means completely identical — the things being compared are one and the same thing, or they match exactly. Similar means resembling but not identical — there are notable similarities but also differences. Grammar also differs: we say the same as (always with “the” and followed by as), while we say similar to (followed by to).
Why do we say “similar to” and not “similar as”?
It is simply a fixed pattern in English: similar always takes the preposition to, not as. Think of it this way: similar is like a comparison adjective that points towards something (similar to), while same makes an equivalence (the same as). Mixing up these prepositions is the most common error with this word pair.
Do we always say “the same” with “the”?
Yes, when same is used as an adjective meaning “identical,” it always requires the definite article the. You cannot say “they are same” or “we go to same school” — you must say “they are the same” and “we go to the same school.” The only exception is in very formal or legal texts where same is sometimes used as a pronoun without “the”: “the document and same shall be submitted...” — but this is highly archaic.
What does “the same goes for” mean?
“The same goes for” is a fixed phrase meaning “this also applies to” or “the same is true of.” It is used to extend a statement to another person or situation: “You must arrive on time. The same goes for your colleagues.” or “I don’t like Mondays, and the same goes for most people in the office.”
How do you use “similar” with nouns vs adjectives?
Similar works as a regular adjective and can appear both before a noun and after a linking verb. Before a noun: “We had a similar experience.” After a linking verb: “Our experiences were similar.” When comparing two things, add to: “Our experience was similar to yours.” To specify the aspect, add in: “similar in many ways.”
What is the difference between “identical” and “same”?
Both identical and same imply complete equality, but identical tends to emphasise that two separate things are indistinguishable from each other, even though they are physically different objects: “The twins are identical” or “identical fingerprints.” Same often implies that it is literally one thing shared or repeated: “We live on the same street” (one street). In practice, identical is slightly more emphatic and formal.
Can “similar” be strengthened or weakened?
Yes. Similar can be modified by degree adverbs: very similar, remarkably similar, strikingly similar (strengthening the resemblance) or somewhat similar, fairly similar, vaguely similar (weakening it). This flexibility makes similar very useful for nuanced comparisons in academic and professional writing, where you need to specify how close the resemblance actually is.
How do you say “same” in phrases like “at the same time”?
“At the same time” is a very common fixed phrase with two meanings: (1) simultaneously — “They both arrived at the same time.” (2) as a discourse marker introducing a contrast — “The plan is ambitious; at the same time, it may be unrealistic.” Other common phrases: at the same rate, in the same way, on the same page, by the same token.
What is “the same old story”?
“The same old story” is an idiom meaning a situation that keeps repeating in a familiar, often frustrating pattern. It implies that nothing has changed and the same problems or behaviours are occurring again: “It’s the same old story — they promise improvements but nothing changes.” The adjective old adds a sense of weariness or exasperation at the repetition.
How are same and similar tested in IELTS and B2 exams?
In IELTS and Cambridge B2/C1 exams, same and similar are tested through sentence transformation tasks (key word transformations), gap-fill exercises, and writing tasks. Key points that are tested: (1) the same as vs similar to (prepositions); (2) the requirement for “the” before same; (3) using similar with degree modifiers in academic writing; (4) recognising when two things are truly identical vs merely comparable.
