konforma

The false seam here is subtler than most, because the pieces really do exist somewhere. Konforma looks like kon- plus formo, and in Latin that is precisely what it was: com- plus forma, having the same shape. But Esperanto has no kon- prefix. The with-prefix in this language is kun-, so a genuine Esperanto build would have produced kunforma, which is not a word anybody uses. Konform- is one imported root, and formo inside it is a fossil rather than a component.

That distinction is the whole point of the Esperanto word-building system. A real build can be taken apart and reassembled by any speaker; a fossil cannot, and treating it as a build produces confident nonsense. The same applies to konsili, konfesi and kontroli: Latin prefixes, Esperanto roots.

Grammatically, konforma takes al: konforma al la reguloj, konforma al la leĝo. The adverb konforme al is the commoner form in official prose (konforme al la statuto), the verb is konformi al, and konformigi is to bring one thing into line with another. Where the meaning is simply matching, responda and kongrua are the plainer choices.
