Tend Doing vs. Tend To Do

Cambridge marks tend + to-infinitive for things that usually happen or people who are likely to behave in a particular way. Keep the separate transitive sense of tend, meaning to care for or attend to something, distinct from the tendency construction.

Quick answer

Use “tend to do” for a usual tendency or likelihood; bare “tend doing” is not the equivalent complement in that sense. Keep the separate transitive sense of tend, meaning to care for or attend to something, distinct from the tendency construction.

Quick tests

Likelihood-or-care test

Does “tend” mean “usually/typically be likely to” before another action?

If yes: Use “tend to + base verb.”

If no: If “tend” means care for or attend to something, use the object pattern required by that separate sense.

Caveat: The transitive care-for sense of “tend” is separate from the to-infinitive tendency construction.

Examples

Example

Prices tend to rise when supply is limited.

Example

I tend to check the totals before sending the report.

The infinitive states a habitual or likely action.

Example

English Usage

Admit Doing vs. Admit To Do

Cambridge documents both admit + -ing and admit to + -ing for acknowledging something. Other passive patterns such as “be admitted to be” are separate constructions.

English Usage

Advise Doing vs. Advise Someone To Do

Both patterns are standard. “Advise waiting” recommends an action generally or in context, while “advise him to wait” names the person who is advised to perform it. A that-clause is another standard option.

English Usage

Afford Doing vs. Afford To Do

When “afford” is followed directly by another verb, standard learner references use a to-infinitive: “afford to do.” An -ing form can appear elsewhere in a sentence, but it is not a like-for-like direct complement after “afford.”

English Usage

Agree Doing vs. Agree To Do

“Agree to do” expresses consent to take an action. An -ing form normally follows a preposition in patterns such as “agree with doing,” which expresses approval rather than the direct promise-to-act construction.

English Usage

Aim Doing vs. Aim To Do

Cambridge documents aim + to-infinitive for intention and aim at for directing effort toward an objective. Do not omit the preposition and present bare “aim doing” as equivalent to “aim to do.”

English Usage

Allow Doing vs. Allow Someone To Do

“Allow” can take an activity as its object, as in “allow smoking,” or a person/thing followed by a to-infinitive, as in “allow visitors to enter.” The patterns answer different structural questions: what is allowed versus who is allowed to do what.
