[Grammar] Infinitive or Gerund

[Checkmate]

"His run/running makes me proud.

Which one should I say? Gerund or Infinitive?

 

[MikeNewYork]

That is a false choice. As written, "run" is a noun and "running" is a gerund noun. There is no infinitive. Without more context, I cannot choose.

 

[Weaver67]

Not a teacher.

As I see it, both are grammatically possible, but what should consequently be used depends on the context.

My friend runs faster than me, I would like to say I'm proud of his talent

My friend runs faster than me. I would like to say I'm proud of his talent.

Note my amendments to your punctuation.

In that context, you could say 'His running makes me proud', but it doesn't sound very natural.
