I can't find proper synonym in 1 and 3 and I'm not sure about punctuation whenusing linkers.Thank you.

1) Teenagers sometimes feel as if they are caught in a No-Man’s-Land (synonym?) between childhood and adulthood.
2) On the one hand, they want to be treated as adults and take responsibility for the actions. On the other hand, they are perhaps not mature enough to deal with the consequences of their actions.
In addition, they don’t want to part from their family (to leave their family.)
3) Parents find themselves in a similar position. They know in their hearts of heart (synonym) that their children have grown up and therefore don’t need the same protection as before.
4) As a consequence, children and parents find it difficult to achieve a new balance in their relationship.

1. I don't think "No Man's Land" fits very well -- http://thesaurus.com/browse/no+man%27s+land -- "the middle ground" is probably more fitting, or maybe "the wilderness" would work.

2. OK

3. delete "of hearts" and it'll be fine

4. OK

1) A possible synonym for "No-Man's-Land" in the context of teenagers feeling caught between childhood and adulthood could be "limbo" or "in-between stage."

To find synonyms, you can use various methods. One way is to use a thesaurus, either online or in print, to search for alternative words with similar meanings. Additionally, you can use search engines to find lists of synonyms or antonyms for specific words.

3) Instead of "hearts of heart," you could use the term "core" or "innermost being" to convey a similar meaning.

When looking for synonyms, it can be helpful to consider the context and tone of the sentence. Thesaurus websites or apps, such as Merriam-Webster or Thesaurus.com, can provide a range of options to choose from.

Regarding punctuation when using linkers (also known as conjunctions or connectors), it is important to follow the rules of grammar and punctuation. Generally, when using a linker such as "and," "but," "or," or "because," you should place a comma before the linker to separate two independent clauses. For example, "They know in their hearts of heart, that their children have grown up..." However, if the clauses are very short and closely related, a comma may not be necessary. It is recommended to consult a style guide or grammar resource for detailed rules and examples of using punctuation with linkers.
