According to the OED, the earliest English use of apotome (alt. spelling "apotomy") with its musical as opposed to mathematical meaning, and of limma, is in 1694 in A Treatise of the Natural Grounds and Principles of Harmony[1] by Church of England clergyman and natural philosopher William Holder. A relevant quote is "Difference between ... Tone Maj. and Limma. Apotome 2187 to 2048". The words are formed from the Greek, with "apo" meaning "away", "tome" meaning "cut" and limma meaning "remnant". So we begin with a major whole tone; the part cut away is the apotome (chromatic semitone) and the remnant is the limma (diatonic semitone).
