同士

どうし

  • head-high (atamadaka): falls after mora 1

How to read it: a line over a kana means the voice is high there, and ↓ marks where it drops. A kana with no line is low. With no ↓ the pitch stays high to the end and does not drop even on a following particle (が, は).

one another, companion, comrade

JLPT N3Commonnoun (common) (futsuumeishi)noun, used as a suffix漢語 · Sino-JapaneseCompoundSound change

Dōshi went from dochi to doshi to dōshi, and its kanji were influenced by Chinese 同志.

Select a part to see every word so far that is taken apart with it.

Wiktionary's text doesn't split this word, so each part is one of its kanji (with the okurigana written after it), with the reading and the dictionary meaning KANJIDIC2 gives that character — a word doesn't always use every sense of its kanji.
