Etymology

Compound of 下 (shimo, “lower”) +‎ 一段活用 (ichidan katsuyō, “monograde conjugation”).

Literally, 下一段 (shimo ichidan) refers to how the inflected endings are located in the gojūon table. 下 (shimo) means the vowel e, which is written beneath the vowel i, the other inflection-related vowel. 一段 (ichidan, “one grade”) means only one vowel is involved, since each 段 (dan, “row”) of the table contains one vowel. Thus, this can be understood as "one-voweled conjugation in e".

Pronunciation

• (Tokyo) しもいちだんかつよー [shìmó íchídáń káꜜtsùyòò] (Nakadaka – [7])
• IPA^(key): [ɕimo̞ it͡ɕida̠ŋ ka̠t͡sɨjo̞ː]
