primus

the word 'primus' is the latin masculine singular form of the adjective meaning "first". it derives from the earlier proto-italic form 'prismos', a superlative built on the prepositional root 'pri' meaning "before". this root can be traced back to the proto-indo-European 'per-', meaning "forward, through, before", which is also the source of english words like 'prime', 'prior', and 'first'. borrowed directly into english, 'primus' retains its classical latin sense of being foremost, often used in formal or specialized contexts such as titles or biological nomenclature to denote the first or most senior in a series.

this word is a direct latin loanword used in its original form. it is a simplex adjective meaning "first".
