曜日
ようび
- flat (heiban)
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).
day of the week
Yōbi is a back-formation of 月曜日 (getsuyōbi), 火曜日 (kayōbi) and the rest.
Taken apart
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.
In a sentence
We don't have the data for this section. The pinned Tatoeba export has no sentence with a translation that uses this word and passes our filter.
