English, however, lacks any sort of case system (except the genetive 's), has very simple conjugations, and a very flexible phonology as far as sounds and consonant clusters allowed. All of this makes English very good at borrowing words and ideas from other languages, since the nouns and adjectives don't really have to decline, and the verbs can be easily formed (we form verbs all the time with English nouns -- in fact, any English -- or whatever language -- noun can be used as a verb.)
