She suggested that he apply / He denied having seen it (C1 Grammar)
When you report a recommendation with suggest, insist, recommend, demand, the that-clause keeps the base verb for every subject — the same form for he/she/it: "She suggested that he apply", not "applies". This is the formal, official choice — reach for it in reports, minutes and academic writing. You will also meet "suggested that he should apply": that is the standard formal pattern in British English, not a casual version of this one, so both belong in a report. Watch out: with suggest and insist the base verb marks a demand. "He insisted that she be told" asks for something to happen; "He insisted that she was told" reports what he claimed. For the negative, put not before the base verb — "insisted that he not be told" (never "doesn't be").
After suggest / insist / recommend: the base verb
"You should apply." → She suggested that he apply for the post.
"Submit it on time." → The professor insisted that every student submit on time.
"Revise the policy." → The committee recommended that the policy be revised.
"He must not be told." → She insisted that he not be told.
Not "She suggested that he applies for the post." — say "She suggested that he apply for the post.". After suggest that, use the base verb apply, not "applies" — no -s even after he/she/it.
Try it: "Sofia must lead the session." The director was firm. Report it with insisted that. Use the base verb. (Leave out the word you don't need.) Answer: The director insisted that Sofia lead the session. — After insisted that, the that-clause uses the base verb: that Sofia lead. "Leads" adds the -s that this formal reporting pattern drops, so it is left out. The base verb is what marks the reported requirement.
After deny / admit: having + past participle
Deny and admit take an -ing form or a that-clause — what they do not take is a plain to-infinitive (never "denied to have seen"). The that-clause is the commonest choice of all: "He denied that he had seen the report". Among the -ing forms, plain seeing is the everyday default in formal writing too, and having + past participle adds one thing: it marks the act as finished before the reporting. Admit also allows to in front of the -ing form: "She admitted to having made an error".
"I didn't see it." → He denied having seen the report.
"I made an error." → She admitted having made an error.
"I never took it." → He denied having taken anything.
Not "He denied to have seen the report." — say "He denied having seen the report.". Deny takes no plain to-infinitive. Use an -ing form (seeing, or having seen for the earlier act) or a that-clause (that he had seen it).
Try it: "I broke the vase," Mateo confessed. Report it after admitted. (Leave out the word you don't need.) Answer: Mateo admitted having broken the vase. — Admit takes no plain to-infinitive, so the "to have" tile is the one to leave out: admitted having broken. The having + past participle points back to the earlier, completed action. Note that admit does allow to in front of the -ing form ("admitted to having broken it"), but these tiles build the shorter version.
After inform / remind: a person, then that
Inform and remind are formal reporting verbs that must name a person before the that-clause: inform / remind + someone + that .... Use inform to report telling news and remind to report prompting a memory — both suit official or careful contexts where "tell" would feel plain. The person object is what sets them apart: say and suggest never take a person this way ("say to someone", not "say someone"), so with inform and remind you name the person directly, with no "to".
"The results are delayed." → The registrar informed the students that the results were delayed.
"Don't forget Friday." → She reminded the team that the deadline was Friday.
"The venue has moved." → Please remind everyone that the room has changed.
Not "The registrar informed that the results were delayed." — say "The registrar informed the students that the results were delayed.". Inform and remind need a person right after them — "informed the students that ...", not "informed that ...".
Try it: "The deadline has moved." The manager told everyone. Inform needs a person right after it, then that. (Leave out the word you don't need.) Answer: The manager informed the team that the deadline had changed. — Inform needs a person directly after it: informed the team that. "To the team" adds an extra word inform does not take, so it is left out. Verbs like inform and remind name a person before the news, with no "to".
