In French, the adjectives ending in -u have a specific ending in the feminine form.
The feminine form of adjectives ending in -u in French
Look at these adjectives:
Il pousse un cri aigu à cause d'une douleur aigüe.He gives a sharp scream because of a sharp pain.
Cet homme ambigu a eu une fin ambigüe.This ambiguous man had an ambiguous end.
C'est un espace contigu dans une maison contigüe.This is a contiguous space in a contiguous house.
Note that adjectives ending in -u (and NOT derived from verbs) become -üe in the written form, but are pronounced in exactly the same way as the masculine form.
(The diaresis, ü, indicates here that the u is pronounced as a separate vowel, otherwise, for example, aigue would be pronounced rather like 'egg' in English.)
Note that before the 1990s, the alternative -uë was the accepted spelling, and is still deemed acceptable now.
