こんなに
こんなに · konnani · JLPT N3 · adverb
so
こんな (this kind, as in これ/ここ) + に (adverb ending) = like this, this much
The こ- words mean this, near me: これ this thing, ここ here, こんな this kind of. Adding に turns it into an adverb, like this or to this degree. Compare そんなに (like that) and あんなに (like that, over there).
