What does familiarised mean?
Familiarised is the past tense and past participle of the verb familiarise, meaning to have made someone — very often oneself — well acquainted with something. It appears most frequently in formal and instructional settings: employees are familiarised with workplace policies, students familiarise themselves with set texts, and travellers become familiarised with local customs. The verb is typically transitive and commonly takes a reflexive object, as in 'she familiarised herself with the rules before signing the contract'. The '-ise' spelling is chiefly British, while American English favours 'familiarized'; the two are otherwise identical in sound and meaning. The word derives from Latin familiaris, 'of the household', via the adjective familiar, which is why its underlying metaphor is one of bringing something close enough to feel like home. It conveys gradual, effortful acquisition of knowledge rather than instant recognition, distinguishing it from merely being aware of something.

Etymology of familiarised
Familiarised derives from the verb familiarise, formed from the adjective 'familiar', which English took from Latin familiaris, meaning 'of or belonging to the household' (from familia, 'family' or 'household servants'). The adjective entered English in the medieval period via Old French, and the derived verb arose later, in the early modern era, alongside other Latinate formations. Cognates sharing the same root include 'familial', 'family', and the noun 'familiarity'.
