Hi Mr. Evans and everyone,
What's your take on the following writings?
"There are four main ideas in relapse prevention. First, relapse is a gradual process with distinct stages. ... Fourth, most relapses can be explained in terms of a few basic rules." (source: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4553654/)
Another example from MW dictionary website:
" The lure of such social acclaim helps some avoid relapse. — Maia Szalavitz, Time, 29 Sep. 2021"
Why is it to appropriate to use relapse without "a" in front? I'm so confused.
