lettering

The word 'lettering' is a transparent English formation built upon the noun 'letter'. The core term 'letter' entered English from Old French 'lettre', which descended from Latin 'littera', meaning a written character or an epistle. The ultimate origin of 'littera' is obscure but may be connected to the idea of a mark or a scratch. The suffix '-ing', of Germanic origin, is a highly productive nominalizer in English. When attached to a noun like 'letter', it transforms it to denote the collective result (the inscribed letters themselves) or the action or process involved (the act of inscribing those letters). Thus, the literal composition "letter" + "action/result of" perfectly captures the modern meanings related to inscribed characters or the act of creating them.

Structure: letter (a written character) + ing (noun suffix) - letter: From Old English, via Latin, ultimately of uncertain origin. Functions as the core noun/root. - ing: From Old English '-ung', '-ing', a suffix forming nouns from verbs, denoting an action or its result.
