Early means happening near the beginning of a period of time, before the expected or usual time, or near the start of the day. It can function as an adjective (an early train) or an adverb (she arrived early).
What Does Early Mean?
Early comes from Old English ærlice, built on ær meaning "before" or "sooner". The same ancient root gives us the archaic word ere (meaning before, still seen in poetry: "ere long") and the comparative earlier. The word has been used continuously in English since before the 12th century, making it one of the language's most enduring time words.
In modern British English, early covers three related ideas: (1) near the beginning of a stretch of time ("early spring", "the early 2000s"); (2) before the expected or scheduled time ("the train arrived early", "an early departure"); and (3) near the start of the day ("an early morning run", "I woke up early").
A key feature of early is that it is one of the few English words that functions as both adjective and adverb without changing form. There is no "earlyly" — the word does the same job in both grammatical roles. This makes it simpler to use than many other time adverbs, but learners sometimes confuse it with soon or before; see the Usage Notes section below for the distinctions.

Usage Notes
Adjective vs Adverb — Same Form
Unlike most English adverbs, early does not add -ly. The adjective and adverb are identical:
- Adjective: an early flight (early modifies the noun flight)
- Adverb: she left early (early modifies the verb left)
Early vs Soon
Early implies a comparison with a reference point — an expected time or the beginning of a period. Soon simply means "in a short time from now" with no reference point implied. You can say "She will arrive soon" without knowing when she was expected, but "She arrived early" only makes sense if there was a scheduled or expected time.
Early on
The fixed phrase early on is used to describe something that happened at the start of a process or situation. It sounds more natural than bare early in narrative contexts: "We spotted the problem early on" (not "We spotted the problem early in the story").
Comparative and Superlative
Comparatives follow the standard pattern for short adjectives: earlier, earliest. Both work for the adjective and adverb roles: "Can we meet earlier?" / "the earliest available slot".
Common Mistakes
Watch Out For
She came earlyly to the meeting.
She came early to the meeting. (No -ly suffix — early is already the adverb form.)
I will call you early. (meaning: in a moment)
I will call you soon. (Use soon when you mean "in a short time", not early.)
He woke up in early.
He woke up early. (Early as an adverb does not take a preposition; say "He woke up early" or "He woke up in the early hours".)
Etymology
Old English ærlice (adverb) and ærlic (adjective), from ær "before, sooner, previously" + the suffix -lic / -lice. Cognates include Old Norse árliga "early", Old High German ēr "before", and Gothic air "early". All derive from Proto-Germanic *airiz, which itself traces to a Proto-Indo-European root meaning "day" or "morning". The modern spelling stabilised during the Middle English period (approximately 1150–1500).
