是 fer shure

Fer shure, THEY will do it correctly every day! (they are down like that)

absolutely! ★★★★☆ 1/2 KANA
是 (fer shure) + 非 (injustice / mistake) = 是非 (absolutely!)

this has 2 meanings:

1) in casual conversation, starting a sentence with 'zehi' means, 'Absolutely!' 'I'll get it done by hook or by crook!' - also, you'll hear 'ぜひおねがいします！' a lot, which means 'Thanks in advance for this favor.' . . . .

2) the propriety or morality of a certain course of action ( the kanji themselves translate to 'right + injustice').
