adverb instead of adjective

[rinotg]

Dear Teacher,

when do I use adverb instead of adjective ?

for example : "It is technically sophisticated market"

They used the adverb and I don't know why they didn't use the adjective

"technical" instead of "technically"

one more example: " We sell competitivly priced product"

again they used the adverb and for my opinion they should have used adjective "Competitive"

please explain

Thanks!!!

Because "technically" is an adverb that modifies the adjective "sophisticated," and not the noun "market." And "competitively" is an adverb modifying the adjective/participle "priced," not the noun "market." [Adverbs ending in -ly don't modify nouns.]
