“Support in” and “support on” can both be used with the verb “support” to indicate that someone or something is providing assistance or backing in relation to a specific matter or issue.
For example:
“We offer our full support in this matter and will do everything we can to help.”
“I’m here to offer my support on any issues you might be facing.”
In both of these examples, the prepositions “in” and “on” are used to specify the specific matter or issue that the support is related to.
It’s worth noting that the preposition “on” is more commonly used to indicate support for a specific issue or matter, while “in” can be used more generally to indicate support in a situation or context.
For example:
“I offer my full support on this matter and will do everything I can to help.” (specific issue)
“I’m here to offer my support in whatever way I can.” (general situation)
