To form gutters or grooves in something; to reduce to a degraded state; or to fit with guttering.
Formed from 'gutter' with the verb-forming suffix '-ize' (from Greek '-izein'). This suffix creates verbs meaning 'to make' or 'to cause to become,' as in 'modernize' or 'organize.'
The '-ize' suffix is incredibly productive in English—you can add it to almost any noun or adjective to make a verb, which is why we can 'gutterize' surfaces, and why English speakers can invent words like 'Zoom-ify' that everyone instantly understands.
