This change in attitude allowed for the growth of many new teaching techniques that are commonly used in classrooms today.
i'm so confused by the "for" in the sentence.
why is there a "for" after "allowed" in this sentence?
allowed for means, provided (an opportunity for the growth of . . . . ).
so, can i omit the "for" here?
In that case it'd mean, permitted the growth . . . . / allowed it to grow. I think the sentence is better with 'allowed for', provided an opportunity; e.g., it provided a certain environment or conditions that led to the growth of . . . .
