compact

compact: There are two distinct words compact in English; both are of Latin origin, but they come from completely different sources. The adjective, ‘compressed’ [14], comes from Latin compactus, the past participle of compingere, a compound verb formed from com- ‘together’ and pangere ‘fasten’. The noun use ‘small case for face powder’ is 20th-century and based on the notion of firmly compacted powder. Compact ‘agreement’ [16] comes from Latin compactum, a noun based on the past participle of the verb compacīscī ‘come to an agreement’. The unprefixed form pacīscī, a relative of Latin pax ‘peace’, gave English pact [15].
=> pact, peace
