割と
わりと · warito · JLPT N2 · adverb
relatively
割 = ratio (割合); 割と = 'by proportion', so it means relatively or fairly
割 means 'proportion', as in 割合. 割と compares something to an expected baseline, so it means fairly or relatively, not absolutely.
割 — 害 (harm, phonetic) + 刂 (knife radical)
A semantic-phonetic compound: the knife radical 刂 gives the meaning 'cut,' while 害 supplies the sound. The original sense was to cut or slice with a blade, which extended to 'divide' and 'allot a share.' Modern uses like 割爱 (give up something dear) preserve this idea of cutting away.
