👉 In linguistics, a subidea (or "sub-subunit") is a smaller unit or group of words in a language that share similar meanings and are closely related to each other. These units can be formed by combining two or more larger units, such as prefixes, suffixes, or phonetic elements.
For example, the word "apple" can be divided into subideas like "p", "a", "l", and "e". Each of these subunits has a different meaning
