The Spanish word 'afiche' meaning 'poster' comes to us through French 'affiche' and ultimately from Latin roots. It can be traced back to the Latin verb 'affigere' meaning 'to fasten to', which itself was formed from the prefix 'ad-' (meaning 'toward') and the verb 'figere' (meaning 'to fix or fasten'). The Latin participle 'affixum' (meaning 'fastened') developed into the French word 'affiche', referring to something fastened or posted up, like a poster. The Spanish 'afiche' borrowed this meaning directly from French, simplifying the spelling by removing one 'f'.

The semantic development from 'something fastened' to 'poster' makes intuitive sense, as posters are items that are typically fastened or attached to walls and other surfaces for display.

In Spanish, you might recognize related words like 'fijo' (fixed, steady) and 'fijar' (to fix, to fasten), which come from the same Latin root 'figere'. When you see an 'afiche' on a wall, you can remember that it's something that's 'fijado' (fixed/fastened) there!

English speakers can connect 'afiche' with several familiar English words that share the same Latin ancestry. Words like 'affix' (to attach or fasten), 'fix', 'fixture', and even 'prefix' all trace back to Latin 'figere'. Just as you might 'affix' a poster to a wall, an 'afiche' is meant to be attached or displayed.
