Pronunciation: [ʌnhˈɑːbə] (IPA) 
The word "unharbour" is spelled with a "u" instead of an "o," as in "harbor." This is because it is a British English spelling, and in British English, words of Latin origin with an "or" ending are often spelled with a "our" ending. The phonetic transcription for "unharbour" is /ʌnˈhɑːbə/, with the stress on the second syllable. It means to leave or depart from a harbor or port.
The term "unharbour" is a verb that is not widely recognized or included in mainstream dictionaries. However, based on its formation, the word can be inferred to mean the act of removing or releasing something or someone from a harbor or harborage.
From a literal perspective, "unharbour" can be understood as the opposite of "harbour," which refers to providing a safe haven or shelter for ships or boats. Hence, "unharbouring" or "unharbour" is the process of undoing or reversing this action, resulting in the act of freeing a vessel from its shelter or removing it from the harbor area.
This term can also be metaphorically extended to suggest disengaging or disentangling something from a state of security, refuge, or confinement. Consequently, "unharbour" could represent the act of liberating or separating someone or something from a state of safety, protection, or being encapsulated within a certain environment or mindset.
Since "unharbour" is not a widely recognized word, this interpretation is based on its potential etymology as an opposite or reversal of the word "harbour." Therefore, it is essential to understand this definition may vary and is subject to individual interpretation until it gains conventional usage and grasps widespread recognition among lexicographers and English language authorities.
