Usage tips
Word formation
The word is derived from 'Alltag' (everyday life) with the ending '-lich' (-ly/-like). 'Alltag' itself literally means 'all days'. So 'alltäglich' (everyday) describes something that belongs to the normal daily routine.
EXAMPLE
Das Kochen am Abend ist für mich eine alltägliche Aufgabe.
Cooking in the evening is an everyday task for me.
Slightly negative nuance
Besides the neutral meaning 'gewöhnlich' (ordinary), 'alltäglich' (everyday) often has a slightly negative connotation. It can also mean 'nothing special', 'boring', or 'banal'.
EXAMPLE
Er flüchtete sich in Bücher, um seiner alltäglichen Existenz zu entkommen.
He escaped into books to get away from his everyday existence.
Typical collocations
Common nouns combined with 'alltäglich' (everyday) include 'Problem' (problem), 'Sorge' (worry), 'Situation' (situation), 'Gegenstand' (object), and 'Routine' (routine).
EXAMPLE
Der Verlust des Schlüssels ist ein alltägliches Problem.
Losing your key is an everyday problem.

antonym
alltäglich vs besonders
especially / special
'besonders' and 'alltäglich' are opposites. 'besonders' describes something that stands out from normal everyday life and therefore catches attention. 'alltäglich' describes something that is normal, usual, and part of daily life. It can be neutral, but sometimes also a little negative in the sense of 'not exciting'. If you want to say that something has special value or is not the same as always, 'besonders' fits. If it is normal and unspectacular, 'alltäglich' fits.
alltäglich
Kleine Probleme im Haushalt sind für ihn etwas ganz Alltägliches.
Small problems around the house are something completely ordinary for him.
besonders
Meine Nachbarin plant für morgen ein besonders schönes Frühstück.
My neighbor is planning a particularly nice breakfast for tomorrow.
