What does vesting mean?
Vesting is the process through which rights or ownership are acquired, most commonly in employment and investment contexts. Employee stock options, restricted shares, and similar benefits may vest gradually, with the holder earning increasing ownership as a specified period of service is completed. The term can also refer to the legal establishment of authority or to the present participle of the verb vest, meaning to clothe someone or confer rights. A vesting schedule sets out when ownership becomes effective, and the term often implies a gradual, condition-based transfer rather than an immediate one. Vesting is especially useful because it captures the idea that valuable rights may depend on time, continued participation, or the fulfillment of stated conditions. Its meaning is broadly similar in British and American usage, although the financial sense is particularly common in corporate compensation and securities discussions.
The process by which ownership, rights, or benefits are acquired or established, especially gradually over time.

Most common in employment, equity compensation, securities, and legal contexts.
The present participle or gerund of vest: to put on a vest, clothe someone, or confer rights or authority.

The legal or administrative sense of conferring authority is formal; the clothing sense is less common in modern usage.
The plural is uncommon; vesting is normally used as an uncountable noun.
"The report compares the vesting patterns used by different employers."
Vesting turns time into ownership: the longer someone stays, the more of their equity becomes truly theirs.

Where does vesting come from?
English vest comes through Old French veste from Latin vestis, meaning garment or clothing. The legal verb sense developed from the idea of clothing someone with authority or putting rights into effect, while the present participle vesting came to name the process of acquiring or granting those rights. Cognate and related forms include divest, invest, vesture, and vestment, all reflecting the broader Latin vocabulary of clothing or equipping.
