Can I just use 'little' instead of 'a little' in this sentence? Like "they're little heavier and little clunkier".
In this case, "a little [adjective]" is used to compare two things. "A little heavier and a little clunkier" is used to show that the Focals are heavier and clunkier compared to normal glasses. Here, "a little" is used before the adjective to modify it. Because it is used to create a comparison, "little heavier and little clunkier" are grammatically incorrect and not appropriate here. "A little" can be used before adjectives and adverbs. Ex. I am feeling a little better today (compared to yesterday). Ex. She is a little thinner than the last time I saw her.
