Kana spelling is standard; usually written in kana.
Kanji spelling with full okurigana; rarely used in practice.
Mixed kanji-kana spelling; rarely used.
Irregular okurigana variant; it is irregular.
Derived from the verb 擦れる (すれる, 'to be rubbed' or 'to become worldly-wise') with the suffix っからし, which adds a derogatory or emphatic nuance. The exact derivation of っからし is uncertain, but it likely intensifies the sense of being worn smooth or hardened by experience.
