Words with the middle part of the word left out are equally few. They may be further subdivided into two groups: (a) words with a final-clipped stem retaining the functional morpheme: maths (mathematics), specs (spectacles); (b) contractions due to a gradual process of elision under the influence of rhythm and context. Thus, fancy (fantasy), ma'am (madam), and fo'c'sle may be regarded as accelerated forms.
