They are all synonyms! However some might have slightly different connotations. For example, immense and tremendous indicate something that is extremely large but tremendous can also indicate some thing that is great or good. Examples: That mansion is tremendous! (extremely large) Seeing Antartica was a tremendous experience. (something great) Hope this helped!

I like your question The difference depends on context All of them mean large but it depends on the context Each word describes something very large but the question is how large this thing that you are describing.. Tremendous is quite different from others. When you say something is Tremendous it means that it is it is sometimes wonderful and it is used to describe intensity. Large: is uses when you want to describe the size of anything. Immen: means is used to describe degree Giant: I heard it on movies used to describe monsters which are very big. So it is used for mythical size as Google says. Massive is also used to describe things that refer to size, amount and it is heavy. Huge is also very big and as has the same meaning as mentioned above. So, it depends on the context and what are you describing.

The more English you know, the more often you use a dictionary. That is to say, an ordinary "English dictionary," one language. One of the important jobs of a dictionary is to give the clearest possible definitions of words that have slightly different meanings. As a learner, what you will find is that there is often one simple, straightforward everyday word, and then a cluster of words around it that have slightly different feelings or shades of meaning. So if you are starting to get interested in understanding differences in meaning between synonyms, I seriously recommend that you start using an English dictionary. The no-cost ones online are OK, and I will say that I am particularly fond of the American Heritage Dictionary--I own a print copy--because I think it has some of the best and clearest definitions. But of course Oxford (Lexico) and Merriam-Webster are fine. Unlike some other languages, there is no official authority for English. It's often hard to say what the differences are, because they involve cultural associations. "Massive" carries the two ideas of size and weight. A hot air balloon might be "huge," but probably not "massive." "Tremendous" often carries the idea of big in a figurative sense, not in linear dimensions. "Newton made a tremendous discovery, one of the biggest discoveries in the history of science." You can't measure the size of the Law of Gravity in meters. "Immense," "huge," and "giant" all mean something beyond "large." If you say that "the land area of Russia is immense," you mean that it is not just "large." Literally, a giant is a person--real or mythical--who is extremely tall, while a dwarf is someone who is extremely short. Therefore, "giant" is often used in contexts to describe the largest of a series of similar things, and often to describe human beings. As always, the use might be figurative. Beethoven was a giant among composers. St. Bernards and Newfoundlands are giant dogs. Betelgeuse is a giant star.
