the word "help"
Even as more troops leave, General Campbell said he is comfortable that international forces are on the right path to helping build a more stable Afghanistan.
Should I say "to helping building" in this sentence? Is "help somebody doing something" right?

Question

Answer

Only one verb can be in the -ing form here and its role in this sentence is modify the main verb.  The main verb is "to build". "Helping" modifies it.

"Help someone doing something". You need to add some words or change "doing" to "do".in this structure."Help someone do something."  " help someone while they are doing something."
