# thank you

> English word · Interjection · IPA /ˈθæŋk ˌju/

## Definitions
1. An expression of gratitude or politeness in response to something done or given.
2. Used as a polite affirmative to accept an offer.
3. A polite dismissal; usually used in professional contexts.

## Etymology
From Middle English thanke yow; as with thank God, praise be to God, and praise the Lord, it was originally a present subjunctive form but is usually not parsed that way in current usage. It has also sometimes been parsed as a prodrop form of (present indicative) I thank you, a mechanism that may plausibly coexist with the other one (instances being variable).
