sounded

The verb 'sound' has a dual etymology, with both strands contributing to the modern uses of 'sounded'. The nautical term, meaning to measure depth, derives from Old English 'sund' (sea, swimming) and was influenced by Old French 'sonder'. The more common meaning, to make a noise, originates from Latin 'sonus' (sound) via Old French 'soner'. The past tense suffix '-ed' is a native English grammatical marker from Proto-Germanic. The convergence of these distinct roots under the single spelling 'sound' is a historical accident, with 'sounded' inheriting both the action of probing the sea and the action of producing or seeming to produce auditory phenomena.

Structure: sound (noise, probe) + ed (past tense suffix) sound: From Old English 'sund' (swimming, sea) and Old French 'soner' (to make a sound), with convergent influence from Latin 'sonus' (sound). In the context of 'sounded' (measuring depth), it relates to the Old English 'sund' (sea, water). In the context of making noise, it relates to the Latin/French root. ed: From Old English '-ede', '-ode', '-ade', a suffix used to form the past tense and past participle of weak verbs.
