The Origin of Instill or Instil
The word instill comes from the Latin verb instillare, meaning to drop in or to pour in. It developed from Latin in- meaning “in” and stillare, meaning “to drop.”
The original physical idea was that something could be introduced drop by drop.
English later developed a figurative meaning. Instead of literally putting drops into something, instill came to describe gradually introducing an idea, feeling, or quality into a person’s mind.
This explains why the word is often connected with things that develop slowly.
For example:
The teacher instilled confidence in her students.
Confidence is not physically poured into someone. The sentence uses the older “drop by drop” idea in a figurative way.
Why Are There Two Spellings?
The difference developed through English spelling conventions.
American English generally uses:
instill
British English generally uses:
instil
The American form follows a spelling pattern that keeps the final l before adding endings.
British English traditionally uses the shorter instil form.
This difference is similar to other British American spelling variations, although the exact pattern can differ from word to word.
