Thank you very much. I knew it was complex . I had never seen the adjectives with rule. Thanks a lot.

- Strict rule| has no single-word adjective opposite that collocates naturally with rule. - Lenient" and "lax" go with people/systems — e.g., lenient teacher, lax enforcement — not with "rule" itself - Permissive | describes environments or parenting styles, not rules - Best opposites of "strict rule": flexible rule, loose rule, soft rule - Guideline" or "recommendation" can replace "rule" entirely when the rule is not strongly enforced.
