Tänulikult

Tänulikult is an Estonian adverb meaning "gratefully" or "with gratitude." It is used to express thanks and goodwill, most often in written communication such as emails and letters. In practice, it can function as a closing formula (a sign-off) or as an adverb describing the manner of an action.

Etymology and form: Tänulikult derives from the adjective tänulik ("grateful"), which itself comes from tänu ("thanks"). The adverbial form is created by adding the suffix -ult, yielding tänulikult meaning "in a grateful manner" or "gratefully."

Usage: The word is common in formal and semi-formal Estonian writing. In speech, variants like "aitäh" or "tänan" are more typical. When used as a closing, it usually appears on its own line or after a short introductory phrase, for example "Tänulikult," followed by the sender's name. It carries a polite, appreciative tone and signals gratitude toward the recipient.

See also: Other closing phrases include "parimate soovidega" (with best regards) and "lugupidamisega" (with respect). The term’s use emphasizes courtesy and acknowledgment in interpersonal communication.
