claim [ME] Latin clamare ‘to call out’ is the base of English claim. It also gives us acclaim [ME] from ad- ‘to’ and clamare ‘to shout’, and reclaim [ME]. This was first used as a falconry term in the sense ‘recall’. The sense ‘make land suitable for cultivation’ is recorded from Late Middle English. Clamour [LME] comes from the same source.
