How to Store multiple values in a column?

I would like to add a column to my table that takes in a set of values like an array. But in the available set of types, I don't see any type that allows adding multiple values in a row.
Available types that I See.


E.g I have a table which has columns words,meanings, synonyms
The column synonym can have multiple values

Heres what I am expecting

|Words | Meanings |Synonyms | something |something |
|---|---|---|---|---|
|word1 | Meaning1 | [synonym1,synonym2] | | |
|word2 | Meaning2 |[synonym1] | | |
|word3 | Meaning3 | [synonym1,synonym2,Synonym3] | | |

I do understand there are hackable ways like storing comma-separated-values, But I am curious if multiple values are allowed if not if there are any plans to add them in the future? or is there any limitation with the database. Sorry if my question is irrelevant I really don't have much idea about the databases.
