(phonology, orthography, grammar) all Japanese morae that can be spelled with 45 single modern kana and 2 historical kana (ゐ/ヰ and ゑ/ヱ) customarily without diacritical marks (゛ and ゜), excluding っ and ん, arranged in a 5x10 table (五十音図 (gojūonzu, literally “table of the fifty sounds”)), used for phonological and grammatical analysis

(orthography) the sort order for kana (historically, mainly for katakana) as arranged in the 五十音図 (literally “table of the fifty sounds”)

Synonym of 片仮名

(phonology, orthography, grammar) the 5x10 table used for arranging all the 47 kana used for the 五十音 (literally “fifty sounds”), whose 列 (“columns”) are arranged by the vowels (/a/, /i/, /ɯ/, /e/, /o/) and 行 (“rows”) are arranged by the consonants (Ø, /k/, /s/, /t/, /n/, /h/, /m/, /j/, /ɾ/, /w/; voiced obstruents and /p/ are customarily not included because they were rarely distinguished in writing); columns are ranked by 段 (“grade”), with the vowel /a/ being the highest grade and the vowel /o/ being the lowest; the missing cells of the や行 (“ya-row”) and わ行 (“wa-row”) are filled with い/イ (i), え/エ (e) and う/ウ (u) taken from the あ行 (“a-row”), in order to represent classical grammatical inflection with modern text (or alternatively, artificially filled with rare kana such as 𛀆/𛄠 (yi), 𛀁/𛄡 (ye) and 𛄟/𛄢 (wu))
