Because the Simple form 'looked' needs a perfective verb, one that means "they took a look", "they took a glance". I guess the best one would be 'spojrzeli', although 'popatrzyli' would work as well.
I know patrzyli is the past tense form for the verb patrzyć, but would "patrzeli" for the verb patrzeć also work here? If not, what's the difference between the two verbs?
Past forms of „patrzeć” are technically correct, but so unpopular in actual language, that I think quite a few natives would correct you, if you were to use them – it might be healthier to think of „patrzeć” as a verb without past forms and use only „patrzyć” in the past tense. ;)
Sorry, but could you please point me to a link to explain why 'wysoki' changes to 'wysocy' for masculine personal plural in the nominative case. Thanks.
What can I say, an adjective ending in -ki in masculine will end in -cy in masculine personal.
Masculine personal is generally usually quite different from the other genders.
Many thanks. I don't think I've seen enough adjectives ending in 'ki' to recognise the pattern!!
