Hi Shauna! Depuis mean: - since/for (from past point until now): Ex. J'apprends cette langue depuis 3 ans. - It can also state a place, as "from": appeler depuis une cabine téléphonique (to call from a phone booth) On the other hand, "pendant" refers to: - "for/through the duration of something". For instance, "Elle a travaillé pendant 10 ans avant de créer son enterprise" (she worked for 10 years before creating her own business). - It can also mean within the duration of something: "Fumer une cigarette pendant la pause" = To smoke a cigarette during break time. - And express a simultaneous event (during/while): "dormir pendant qu'il fait nuit" = to sleep while it's dark/during night time. Pour is translated as "for" or "to". Same as english, it is used to state a purpose, a condition, a destination, a cause, a length of time or the time needed to do something. Regarding the latter, you'd say "it took me 3 hours to get home" = j'ai mis 2 heures pour rentrer à la maison. Or you could say: "j'en ai eu pour 2 heures". Hope this helps!
