1. Overview and Core Grammatical Roles

   In advanced English grammar, both gerunds (verb + -ing) and infinitives (to + base form) function as non-finite verb forms that occupy nominal positions in sentences. Despite their verbal origins, they act primarily as subjects, direct objects, and subject complements.

   1. Syntactic Functions

   • Subject: Negotiating international contracts requires acute legal acumen. (Gerund as subject)
     To renege on such commitments would jeopardize future funding. (Infinitive as subject; typically more formal or emphatic)
   • Direct Object: The board decided to postpone the merger. / The analyst enjoys interpreting complex datasets.
   • Subject Complement: Her principal ambition is to lead the humanitarian mission. / The primary concern remains mitigating structural deficits.
   • Object of a Preposition: Only gerunds follow prepositions directly: They succeeded in securing substantial venture capital. (Never: *in to secure)

   Verb Complementation Patterns

   The choice between a gerund and an infinitive following a main verb is dictated by lexical selection rules.

   Verbs Exclusively Followed by Gerunds

   Certain verbs typically express completed, ongoing, or hypothetical activities:

   • Admit, anticipate, avoid, consider, defer, deny, entail, postpone, resist, resent, risk:
   • Example: The CFO avoided disclosing preliminary quarterly estimates prior to verification.

   Verbs Exclusively Followed by Full Infinitives

   These verbs frequently refer to intentions, potential future states, or decisions:

   • Afford, agree, aim, claim, consent, demand, hesitate, intend, resolve, strive, undertake:
   • Example: The administration undertook to restructure the regulatory framework within twelve months.

   Verbs Followed by Object + Infinitive

   Certain transitive verbs require an explicit object before the full infinitive:

   • Advise, compel, enable, forbid, implore, instruct, prompt:
   • Example: Fiscal constraints prompted the committee to scale back capital expenditures.

   Verbs Signifying Meaning Changes

   Several dual-complementation verbs permit both gerunds and infinitives, but the choice fundamentally alters the chronological sequence or aspectual meaning of the action.

   Key Contrasts

   • Remember / Forget:
     • Gerund: Backward-looking; recalls a past occurrence.
       Example: She remembers submitting the proposal ahead of the deadline.
     • Infinitive: Forward-looking; refers to a duty or task yet to be performed.
       Example: Remember to submit the revisions before the symposium commences.
   • Stop:
     • Gerund: Terminating an ongoing activity.
       Example: The researcher stopped speculating once empirical evidence emerged.
     • Infinitive: Pausing one activity in order to initiate another (infinitive of purpose).
       Example: The delegates stopped to review the newly drafted treaty clauses.
   • Regret:
     • Gerund: Expressing remorse for a past deed.
       Example: He regretted revealing confidential survey methodology prematurely.
     • Infinitive: Announcing unfortunate news formally.
       Example: We regret to inform applicants that grants have been fully allocated.
   • Try:
     • Gerund: Experimenting with a method to see if it yields results.
       Example: Try adjusting the centrifuge speed to improve separation.
     • Infinitive: Making an effort to accomplish an arduous or uncertain objective.
       Example: The team tried to isolate the pathogen despite equipment failure.

   Advanced Voice and Aspect Variations

   At advanced levels, non-finite clauses integrate voice and temporal anteriority through auxiliary verbs.

   1. Perfect Gerunds and Infinitives

   Used to clarify that the non-finite action preceded the time of the governing verb:

   • Perfect Gerund (having + past participle):
     The executive admitted to having authorized the unauthorized transaction.
   • Perfect Infinitive (to have + past participle):
     The manuscripts are believed to have perished during the fire of 1842.

   2. Passive Gerunds and Infinitives

   Shift focus to the recipient of the non-finite action:

   • Passive Gerund (being + past participle):
     Diplomats resent being bypassed in high-level geopolitical dialogues.
   • Passive Infinitive (to be + past participle):
     Crucial data sets remain to be analyzed by the independent audit panel.

   3. Perfect Passive Combinations

   • Form: having been + past participle / to have been + past participle
     Example: The artifact was reputed to have been discovered along the Silk Road millennia ago.
