Pronunciation and morphology notes
Eleven introduces the Japanese build-by-place rule: ju (10) + ichi (1) = ju-ichi. No special word as in English (eleven, twelve). The pattern continues identically through 19: ju-ni, ju-san, ju-yon, ju-go, ju-roku, ju-shichi or ju-nana, ju-hachi, ju-kyu. Above 20, the form switches to tens-digit + ju + ones-digit: ni-ju (20), ni-ju-ichi (21).
