What does fulfill mean?
Fulfill is a transitive verb meaning to carry out, complete, or satisfy something — whether that is a duty, a promise, an order, a set of requirements, or a deeply held ambition. In its most concrete form it appears wherever obligations matter: contracts are fulfilled, roles are fulfilled, orders are fulfilled. In its more abstract and emotionally resonant sense, to fulfill means to bring to realization one's potential or purpose, which is why phrases like 'fulfilling career' and 'a fulfilling life' dominate discussions of happiness and motivation. The word carries strongly positive connotations of completeness, reliability, and achievement. It derives from Old French 'fulfilir', itself rooted in the Latin 'plenus', meaning full, so the idea of wholeness is built into its history. British spelling usually drops the second 'l' ('fulfil'), while American usage keeps both. Few verbs so neatly bridge the practical world of commitments and the inner world of satisfaction.
verbTo fulfill is to carry out or complete a duty, promise, order, or expectation; more broadly, to satisfy a requirement, condition, role, or personal aspiration.
- To carry out or complete a duty, promise, order, or obligation.
- To satisfy or meet a condition, criterion, requirement, or purpose.
- To realize or bring to completion a personal potential, ambition, or sense of purpose (often as 'feel fulfilled').

Fulfill comes from the Latin 'plenus' — meaning full — so every time you fulfill a dream, you are literally making it whole.

Etymology of fulfill
Fulfill entered English from Old French 'fulfilir' (modern 'fulfrir'/'accomplir' lineage aside), ultimately derived from Latin 'plenus', meaning full. The underlying sense is thus 'to make full' — to bring something to completeness. English adopted the word around the early modern period, and it has since developed two main strands of meaning: discharging duties and realizing aspirations. Cognates sharing the Latin root include 'plenty', 'plenary', and 'plenitude'.
