Languages always differ to some extent in the diapason of their word stock. One language may have a name for an item of vocabulary that corresponds to real-life differences lacking in another. Such is the case, for instance, of English finger and toe to name digits on human hands and feet, respectively, which is lacking in Russian. The latter uses the word palec (палец) for both. Although the word without further specification refers to hands, when a differentiation is required a clarificatory phrase is used to designate the anatomical item, namely пальцы на руках ‘fingers’ and пальцы на ногах ‘toes’.

A unique case of lexical specificity is to be observed with a triplet of compound adverbs (preposition + verbal stem + feminine accusative desinence) in Russian that designate whether one puts the sugar in the cup/glass of tea or drinks it with the (piece of) sugar between one’s teeth. (Tea drinking is an activity Russians are traditionally very fond of.) Thus, when sugar is used in one’s tea, the appropriate phrase is внакладку (vnakládku) ‘placing in’. When the sugar is held between the teeth while drinking tea, the word is вприкуску (vprikúsku) ‘biting in’. And finally, in jocular use, when no sugar is taken at all with one’s cup of tea, the word is вприглядку (vprigljádku), which means something like ‘while eyeing [it]’. This three-way differentiation between drinking tea with or without sugar amply testifies to the wide-spread idiosyncrasies of word usage observed across languages.
