invitation

The word "invitation" entered English in the early 15th century from Old French invitacion, which itself derived from Latin invitationem (nominative invitatio), meaning "an invitation, incitement, challenge." This noun was formed from the verb invitare, "to invite, treat, entertain." The verb invitare is composed of the prefix in- (here meaning "in, toward") and the root -vitare. While the exact origin of -vitare is debated, it is traditionally linked to a Proto-Indo-European root meaning "to go, pursue," which evolved in Latin to carry the sense of "to summon or call forth." Thus, the literal logic of the morphemes is "a calling in" or "a summoning toward," which perfectly encapsulates the modern meaning of a request for someone's presence or participation.

Structure: in (in, on) + vit (call) + ation (noun suffix) - in: Latin origin, meaning "in, on, upon". A prefix indicating direction or state. - vit: From Latin vitat-, the stem of vitare (to avoid, shun), but influenced by the root of invitare (to invite). In this word, it carries the core sense of "call" or "summon". - ation: Latin suffix -ationem, forming nouns of action or state from verbs.
