desire: [13] The underlying etymological meaning of desire is something of a mystery. Like consider, it comes ultimately from a base related to Latin sīdus ‘star’, but the links in the semantic chain that would lead us back from ‘desire’ to ‘star’ have not all been successfully reconstructed. It does at least seem, though, that before the word denoted ‘wanting’, it signified ‘lack’. English acquired it via Old French desirer, but has also gone back directly to the past participle of Latin dēsīderāre for desideratum ‘something desirable’ [17].
