How to use thank you
Learner’s notesIn plain EnglishWhat you say when someone has done something nice for you.
Neutral in every register. Adding "so much" or "very much" raises the warmth; a flat "thank you" delivered coldly can read as sarcastic or dismissive.
Keep it two words as an expression, and hyphenate it only when it sits in front of a noun: "Thank you for the gift" but "a thank-you gift".

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).
