sawed

The modern verb 'to saw' originates from the Old English noun for the tool, 'sagu', which itself has Proto-Germanic roots. This noun was converted into a verb in Middle English through the common linguistic process of zero derivation, where a word changes its part of speech without adding an affix. The addition of the regular past tense suffix '-ed', a standard feature inherited from the Germanic language family, creates the form 'sawed'. Thus, the word's journey reflects a shift from a concrete noun to an action verb, followed by the application of a standard grammatical inflection.

The word 'sawed' is the past tense and past participle form of the verb 'saw'. The base verb 'saw' is a simplex word derived from Old English 'sagu' or 'saga', meaning a cutting tool. The suffix '-ed' is a productive inflectional morpheme of Germanic origin used to form the past tense and past participle of regular verbs.
