Tipofthetongue, commonly written as tip-of-the-tongue (TOT), is the phenomenon in which a person cannot retrieve a known word or name despite a strong feeling that retrieval is imminent. People experiencing TOT often remember partial information about the target word, such as its semantic meaning, grammatical category, syllable count, or the initial sounds, and they may be able to produce related or similar-sounding candidates. TOT is a common, normal part of language production and can affect people of all ages, though it tends to occur more frequently with aging or higher cognitive load.

The prevailing account of TOT posits a retrieval failure within the lexical access process. While semantic information and some phonological features may be active, the complete phonological form of the word remains inaccessible at the moment of the block. This partial activation can yield related terms or partial clues (such as the initial sound or rhymes) that sometimes help resolve the impasse. Neurocognitive studies point to a network involving left frontal and temporal regions, consistent with retrieval search, monitoring, and phonological encoding processes.

Resolution of TOT states often occurs spontaneously or with external cues. Providing semantic hints, phonological cues, or initial letters can trigger successful retrieval. Reducing interference, allowing time for retrieval, and engaging in deliberate practice of word retrieval can also help, particularly for individuals who experience frequent TOT episodes. TOT is viewed as a normal variant of language production rather than a clinical disorder, though its frequency and impact can vary among individuals and across conditions.
