Pronunciation: [hˈa͡ɪ͡əɹ ˈɒn] (IPA) 
The correct spelling of the phrase "hire on" is /haɪr ɒn/. The word "hire" is spelled with an "i" before the "e" because it follows the typical English phonetic spelling rule stating that long vowels are spelled with the vowel's name as in "pine", "be" or "who". The preposition "on" is spelled with just one "n" because it is a monosyllabic word with a short vowel sound. "Hire on" means to become an employee or to start a job.
"Hire on" is a phrasal verb that refers to the act of employing or engaging someone on a temporary or permanent basis. It is commonly used within job contexts, describing the process of securing the services of an individual for a specified period or position.
The term "hire on" implies both the establishment of a formal contractual relationship and the assumption of work responsibilities. When someone is "hired on," it means they have been selected by an employer or company to perform a particular role, with duties and expectations outlined. This may involve signing an employment contract or agreement that details the terms and conditions of the engagement, such as wages, benefits, working hours, and any specific job requirements.
The phrase can be used in both professional and informal settings, with the intention of bringing someone into an organization or team for a specific purpose. It can encompass various employment arrangements, ranging from full-time positions to part-time jobs or temporary contracts. Individuals who "hire on" are typically subject to company policies, rules, and regulations, and their remuneration is typically determined by the terms agreed upon.
Overall, "hire on" represents the process of engaging someone for work, whereby they are selected, contracted, and placed in a position to contribute their skills, knowledge, and expertise to an organization or project.
The phrase "hire on" can be understood as an extension of the word "hire". The etymology of "hire" can be traced back to the Old English word "hyrian", which meant to engage someone's services or to obtain the temporary use of something. This word derived from the Proto-Germanic word "hurjaną", which had a similar meaning. Over time, "hire" evolved to refer specifically to the act of employing someone in exchange for wages.
The addition of the preposition "on" in "hire on" serves as a phrasal verb particle common in English. In this instance, "on" functions as an intensifier, often emphasizing the completion or commencement of an action. Therefore, "hire on" implies acquiring employment or the act of joining a company or organization in a more emphatic way than just "hire".
