Word Origins & Etymology

Then derives from Old English 'þonne/þanne' (at that time), related to Proto-Germanic '*þan.' It has always indicated time or sequence in English.

Than also comes from Old English 'þonne,' but in its comparative function. Historically, 'then' and 'than' were the same word that split into two spellings to distinguish two meanings.

🔗 The Connection

These words were literally the same word in Old English. The split happened gradually from the 17th century onward, when printers began standardizing 'than' for comparisons and 'then' for time. This shared origin explains why they remain so confusing.

Why Do People Confuse Them?

Then and than are near-homophones: in casual speech, both are often pronounced as /ðən/ with a reduced schwa vowel. The distinction ('e' for time, 'a' for comparison) is purely a spelling convention that was only standardized about 300 years ago. Because they were historically the same word, the brain's language center treats them as interchangeable during rapid writing.
