serve: [13] Latin servus ‘slave’ has been a rich source of English vocabulary. It is the direct ancestor of serf [15] (and of the second syllable of concierge [17]). but it is its derivatives that have made the most numerous contributions. From the verb servīre ‘serve’ come deserve, dessert, sergeant, servant [13], serve, and serviette [15] (but not, despite the similarity, conserve, observe, preserve, reserve, etc, which go back to the unrelated Latin servāre ‘keep, protect’). Servītium ‘slavery’ has provided service [12] and its derivative serviceable [14], while from servīlis ‘slavish’ comes servile [14].
