Hi Leslie, The rule we're looking at here is "causative verbs". There are only four! Let, have, help and make. The pattern is this: [causative verb] + [object] + [base verb] ...so the second verb is always in the base form. So, [make] + [my money] + [work] ... Here's a slightly adjusted sentence, so the form of the first verb doesn't confuse you. "This investment plan makes my money work for me." The conjugation has already happened, so we don't do anything to "work" (which, anyway, is connected to the object - money - and not the subject).

It's definitely not conditional. ;)

So is it conditional or causative? Very interesting set of answers. Everybody thank you so much for your input.

Make my money work for me. First of all, this is a command so the "work" in "..my money work.." is conditional. My money works for me. This is a statement, work is not conditional.

Hello Leslie! To make something work is a phrase. So the verb "work" is not conjugated and on top of that it's said in the imperative so the verb "make" is not conjugated. Otherwise here are a few other examples "I make things work" "She makes it work" As you can see in these cases you have to conjugate the verb "to make". In your second example the verb "work" is used normally and it's conjugated according to the object of the sentence. I hope this helps!:)
