tanka
Synonym discussion
Sense: noun/1
A tanka is a specific Japanese poem form, so it is much narrower than poem or verse, which can describe almost any kind of poetry. Compared with a haiku, a tanka is longer and usually has five lines instead of three, giving the writer more room for feeling or reflection. A sonnet is also a fixed form, but it belongs to a European tradition and is much longer than a tanka. Use tanka when the Japanese five-line pattern matters. Use poem or verse when the exact form is not important.
Etymology
The poetry sense comes from Japanese tanka, literally meaning a short song. In English, the art sense is also used as a spelling of thangka, a Tibetan religious painting on cloth.
