I would like to ask on the usage of the verbs "to try out " and " to try "
For example, when we say :
I am going to try a diet out this month and I hope it is going work to help me lose 10 kg in a month.
I am going to try a diet this month and I hope it is going work to help me lose 10 kg in a month.
Is there a difference in terms of meaning.I heard there could be regional differences in usage as well, is it true ( I mean maybe it is ok in the US but it is not common in the UK)
When I look up to for "to try out" on an online dictonary , it says "to test or use somebody/something in order to see how good or effective they are". So I noticed that we need a thing to try it out.But ,I reckon, another verb follows after only "try" like
-I am going to try to run 10 miles today.
I would like to ask you to check my other sentences if they are ok in this sense.
1) Hey, have you heard? Famous chain kebab shop has launched a new branch in the town. The restaurant itself is pretty big and the prices are 50% off for today. So I am going to try it (out) today .
2) I am planning on buying new stuff for learning English. I found out there is a video series which is provided by Oxford University. But before I buy the whole DVD set, I am going to try out the demo first in order to see if they are useful for me.
3) I will try out a new antivirus software as the last one I bought was not able to deter viruses from infecting my computer.
4) I have bought new chemical-proof work clothes so the workers can be protected from hazardous materials in the factory. Have every worker try them out, and make a report if it works for us.
5) I will try out the LG3 smart phone to see if it is worth buying.
6) I will try to use this grammar book for my dissertation this time because the old one is pretty out-of-date.
( I am aware of there is another thread on this topic on the site.I have written down these questions after I had read it, because it doesn't answer my questions sufficiently. This question is not dublicate, more like extended version of available one)
Thanks in advance!
