The antonym of the word 'theoretical' is 'experimental'.

The word "theoretical" refers to something based on theory rather than practice or experience. It involves concepts or ideas that are abstract or hypothetical, often not yet tested or applied in real-world situations. On the other hand, "experimental" refers to something that is based on or derived from actual experiments or real-life application. It suggests practical testing and observation, rather than abstract thinking.

• Experimental: The opposite of theoretical, experimental refers to something that is grounded in practice, testing, and real-world applications. It focuses on the hands-on, practical side of learning or investigation.

• Bookish: This term relates to someone who is more concerned with books and theoretical knowledge, rather than practical or experimental knowledge. However, it doesn't specifically mean the opposite of theoretical, as it still suggests a focus on learning from books rather than practical application.

• Logical: While logical may sound related to theoretical, it is not its direct antonym. Logic can be part of both theoretical and practical fields, so it doesn't oppose the concept of theoretical in the same way "experimental" does.

• Impartial: This refers to being neutral or unbiased, which is unrelated to the distinction between theoretical and experimental. It doesn't serve as the antonym of theoretical.

Therefore, the correct antonym is experimental, as it directly contrasts with the abstract, untested nature of theoretical knowledge.
