something
Only a non-expert could say that.
Different issue. Pronouns are very irregular in very many languages, ordinary words, including prepositions, possessives and contractions, are a much different matter.
Children are sufficiently important in English to have much greater variety of words. e.g. (newborn, infant, toddler, preschooler, school kid, tween, teen {and subvariations}) not all of which have exact cognates in other languages.
We do all of these things in English as well.
That will get you up to comprehensible spoken English, but not to proper fluency; let alone to technical or contracting English.
