Plural of Thanks
The gratitude noun “thanks” belongs to the group of nouns used only in the plural in ordinary modern English. For a single expression, English normally uses wording such as “a word of thanks,” “a thank-you,” or “an expression of thanks” rather than treating “thank” as the regular singular noun.
“Thanks” is already a plural-only noun when it means expressions of gratitude. It normally takes plural form and does not use an ordinary singular “thank” for one expression of gratitude.
