What does くっ change to the meaning?

2 Answers 2


つける ~ join, put, wear... it means to put one thing onto one another.

くっつける ~ stick... so it means to put something onto one another so that it does not come off.

The くっ from くっつける comes from 食い.



くっ is a variant of the prefix 食{く}い~. So the original form would have been 食い付ける.

When a verb is prefixed with the morpheme 食い~ (or variants like くっ~), it adds an additional meaning to the base verb. As is obvious from the kanji, this can be the addition of a literal action of eating, chewing, or using the mouth/teeth. But it can also be a figurative meaning which adds an idiomatic sense to the base verb. From the examples below, you can see that the prefix 食い~ seems to add volition and/or intensity to the original action. It is as if conjuring up the image of teeth brings with it a certain ferocity which lends a sense of struggle (or at least intent) to that original verb.

込{こ}む be crowded → 食{く}い込{こ}む encroach, erode, bite into

つける attach → くっつける stick together
