Pronunciation: [ɡˌə͡ʊ dˈiːp ˈɛnd] (IPA) 
The phrase "go deep end" is often mistakenly spelled as "go off the deep end". The correct spelling uses the preposition "into" instead of "off", creating "go into the deep end". This phrase refers to losing control or becoming irrational. In IPA phonetic transcription, the word "deep" is spelled as /diːp/, with a long "e" sound and a voiced "p". The word "end" is spelled as /ɛnd/, with a short "e" sound and a voiced "d".
The phrase "go deep end" is a idiomatic expression that typically refers to behaving in an irrational, extreme, or uncontrollable manner. It is often used to describe someone who becomes overly emotional, agitated, or loses their composure in a particular situation. When someone "goes deep end," they abandon their rational thinking and act impulsively, without considering the consequences of their actions.
This phrase is derived from the imagery of a person diving into the deep end of a swimming pool. Just as diving into the deep end is an abrupt and drastic action, going deep end describes someone suddenly and dramatically losing control.
The concept of going deep end can be applied to various scenarios. For example, it may describe someone experiencing an emotional outburst, engaging in reckless behavior, or reacting excessively to a perceived provocation. It is important to note that going deep end differs from expressing strong emotions in a controlled manner, as it denotes an extreme and often irrational response.
Overall, the phrase "go deep end" encapsulates the idea of an individual disregarding their usual behavior or mindset, and succumbing to impulsive or irrational behavior instead.
