Tips to remember the structure:
• In Korean, verbs can be turned into descriptive adjectives to modify a noun by using their attributive form. Here, 참여할 ("will participate") modifies 수 있는.
• The phrase “할 수 있는” combines the ability construction V + 수 + 있다 into an adjective phrase meaning "able to (do V)."
• “것” (often contracted to 게) is used to nominalize the preceding clause (turn it into a “thing” or “fact”), making it the subject of the sentence.
• The sentence follows the pattern: [Subject] + [Modifier clause (able to participate)] + [is important].

Alternate ways to say "It is important that he can participate":
• 그가 참여할 수 있다는 것이 중요해요.
 – Here, “다는” is added to explicitly indicate a reported clause: "the fact that he can participate is important."
• 그가 참여할 수 있는 점이 중요해요.
 – “점” (jeom), meaning “point/aspect,” is used instead of “것” for a slightly different nuance while keeping the meaning similar.
