Grammar
N3 particle

To the extent 〜ほど

Meaning

Gives a yardstick for how much — "so ~ that …", "to the extent of ~".

Formation

Notes

With a negative it makes a comparison: 今年は去年ほど暑くない ("not as hot as last year") — and that form is ALWAYS negative. Otherwise it measures a degree: 立てないほど疲れた. More vivid than くらい, which is closer to a plain approximation.

I was so tired I could not stand.

Breakdown
cannot stand to the extent that got tired

This summer is not as hot as last year.

Breakdown
this summer as much as last year is not hot (negative required)
