Causes for Semantic Changes
The English Word by Arnold
Linguistic and extralinguistic causes
Meaning of words are relatively stable. If they changed too often, communication would be impossible. Semantic changes are slow and we speak of semantic change form a diachronic point of view. But semantic changes are initiated in context, on the synchronic level. On the synchronic level we speak of deviation of meaning only.
