The term 'prefix with lingual or lateral' refers to two prefixes, TRI- and uni-, which are used to describe words related to having three or one sides, respectively. TRI- is derived from the Greek word for three, while uni- is derived from the Latin word for one. These prefixes are commonly used in scientific and medical terminology to describe objects or processes that involve three or one sides. For example, a trilateral shape has three sides, while a unilateral process involves only one side.
