Question

Where is the primary stress in the word: blossom? a. 2nd syllable b. 1st syllable​

Answer 1

The word blossom has two syllables:

blos-som

As apparent, the 1st syllable is much more stressed than the 2nd one, as it contains the initial plosive consonant combination of "blo"

I hope this helped, your answer is that the 1st syllable is the stressed syllable.
