[Grammar] Provided that vs as long as vs on condition that

[juyjhj]

Are these three expressions interchangeable, or do they have different meanings? For instance, in these sentences is it possible to use any of the three?


-On condition that/as long as/provided that he took voice classes, he would become a great singer.

-People usually catch diseases, provided that/as long as /on condition that they are malnourished.

-Provided that/as long as/on condition that you like sweet things, it must be delicious.

-People usually catch diseases, provided [space] that/as long as /on the condition that they are malnourished.

-Provided [space] that/as long as/on the condition that [space] you like sweet [space] things, it [space] must be delicious.

Welcome, Juyjhj!

If would work better in all of those.

Before we discuss the differences between the expressions, tell us where you found them. Did you make them up?

Thank you for your reply! I apologize for all the mistakes, but I was in a hurry. I found these sentences in an exercise;

-People usually catch diseases, if they are malnourished.
-If you like sweet things, it must be delicious.
-Nino doesn't want to take voice lessons. If he took them, he would become a great singer.

I was supposed to rephrase, if possible, the normal if-clauses with one of the following expressions: given that/but for/without/provided that/unless/on condition that/even if/suppose/supposing. I think that in these three sentences only provided that, as long as or on condition that might work, but I don't know which one.

Thank you for your help! I apologize for all the mistakes, but I was in a hurry. I saw these sentences in an exercise.

-People usually catch diseases, if they are malnourished.

That doesn't need a comma.

-If you like sweet things, it must be delicious.

That doesn't make sense, and it's ungrammatical.

-Nino doesn't want to take voice lessons. If he did take voice lessons he would become a great singer.

I was supposed to rephrase, if possible, the normal if-clauses with one of the following expressions: given that/but for/without/provided that/unless/on condition that/even if/suppose/supposing.

I'm not sure what you're supposed to do.

Take your time on the forum. Read your own posts through at least twice before posting. If you set the spellchecker on your browser to English, it will underline spelling and grammar errors.

Was it from a book of exercises for students? If so, you must tell us the title of the book and the name of the author. This is always the case when you quote someone else's words.
