Which term means 'under the tongue'?

• A. sublingual
• B. supplement
• C. suppress
• D. symmetric

Answer: (A)

Understanding terms like sublingual relies on prefixes and roots that describe location. Sub- means under or beneath, and lingual comes from the tongue. When you combine them and add the -al ending, you get sublingual, an adjective describing something located under the tongue. In medical contexts this term is used for things like a sublingual tablet that dissolves under the tongue for rapid absorption. The other options don’t relate to location under the tongue: supplement implies added material, suppress means to restrain, and symmetric refers to having balanced sides.
