No one is biologically disposed to speak a particular language.
People always tinker with the way they talk, and as the tinkering accumulate on different sides of the river, mountain range, or no man's land, the original language slowly splits in two.
All languages have a stock of morphemes and a set of conventions for assembling them into meaningful combinations such as complex words, phrases and sentences. Words can accept suffixes, prefixes and insertions. All languages have irregularities.
In German, verbs have 3 forms:
Infinitive
Preterit
Participle.
Irregulars, as in English, are stores in an associative memory.
Each mixture arises when unique historical events- conquest, immigration, trade, fads in speaking- are handled by an unchanging mental tool kit, which contains a frequency and similarity- loving associative memory and a promiscuous combinatorial grammar.
