Hello Rafal. I like your effort. I will contribute: The examples that you posted here, require one last element. The form is: //// subject - gains - object My pain gains _________ My satisfaction gains _________ * The noise gains _________ The temperature gains ____________ * His anger gains ________ in almost all these, you can use the word +intensity+ Allow me to show you some other examples that follow the same form: You gained confidence We gained a friend She gained an enemy He gained an accomplice I gained weight I gained muscle I gained extra streams of income this past year

Hello there “Gain” is usually used when something can be measured with a number. The value of the investment gained over summer The speed of the car was gaining He had gained weight The plane gained 1000 feet in altitude ^ these are all good English Pain gaining is wrong. We would say “increased” here. Correct: the noise levels gained 20 decibels Incorrect: the noise gained [increased would be better here] Also: in British English we often say “He put on weight”

To the first question: "I gained weight" is correct. We would not ordinarily used "my" in the sentence. Weight is not an object we possess; it is a condition or state. The second question: We would ordinarily not use gain in this sense. "My hunger is increasing" or "I'm growing hungrier by the minute" or "I'm getting hungry" are the most frequently used. To the third question: Someone gains something is the most common structure. It depends on the statement being asked, however. No hard and fast rule applies to this.

Are you saying that these examples are incorrect? My pain gains The something's value gains My satisfaction gains The noise gains The temperature gains His anger gains
