Need of synonym,synonyms of need of

Similarity: Both "need of" and "requirement for" imply that something is necessary or essential. They are used to express that a particular thing or condition is needed for a certain purpose or to achieve a certain outcome. For example, "There is a need of/requirement for more staff to complete the project on time" indicates that additional staff are necessary for the successful completion of the project.
Usage difference: "Requirement for" often suggests a more formal or specific necessity that is usually defined by rules, regulations, or specific circumstances. It is commonly used in professional, academic, or technical contexts. For instance, "The requirements for this job include a degree in engineering and five years of experience." "Need of" is a bit more general and can be used in a wider range of contexts, including both formal and informal situations.

Similarity: In some cases, "need of" and "demand for" can have a similar meaning, especially when referring to the desire or necessity for something in the market or in a particular situation. They both imply that there is a call or a requirement for a certain product, service, or resource. For example, "There is a high need of/demand for housing in this area" shows that there is a strong desire or necessity for housing due to factors like population growth.
Usage difference: "Demand for" is more often used in the context of economics, business, or market analysis to describe the quantity of a good or service that consumers are willing and able to buy at a given price. It emphasizes the market aspect and the purchasing power or desire of consumers. "Need of" is more about the general necessity or lack of something, which may not always be related to market forces. For example, you might say "I'm in need of a new pair of shoes" simply because your old ones are worn out, not because there is a market demand for shoes.

Similarity: "Want of" and "need of" can both express a lack or deficiency of something. They can be used to indicate that a particular thing is lacking and is desired or required. For example, "The plant died due to a want of/need of water" shows that the lack of water was the cause of the plant's death.
Usage difference: "Want of" is a bit more old-fashioned or literary in tone compared to "need of". It is less commonly used in everyday modern English. "Need of" is more versatile and widely used in various spoken and written contexts. Also, "want" can sometimes imply more of a desire or wish, while "need" emphasizes the necessity more strongly. For example, "I want a new car" is more about a personal desire, while "I need a new car" implies that it is essential for some reason, like for commuting to work.

Similarity: "Necessity for" is very close in meaning to "need of". They both convey the idea that something is essential or indispensable. For example, "There is a necessity for/need of proper ventilation in the building" emphasizes that proper ventilation is crucial for the building's functionality and the health of its occupants.
Usage difference: "Necessity for" often emphasizes the importance and indispensability of something in a more serious or urgent way. It is commonly used in discussions about important matters, such as the necessity for safety measures in a workplace. "Need of" can be used in a more casual or general way to express any kind of requirement or lack.

Similarity: "Requisite for" and "need of" both imply that something is required or necessary. They are used to indicate that a particular thing or quality is essential for a specific purpose or to meet a certain condition. For example, "Good communication skills are a requisite for/need of this job" shows that good communication skills are necessary to perform the job well.
Usage difference: "Requisite for" is more often used in a formal or technical context to refer to a specific requirement that is necessary to achieve a particular goal or fulfill a particular role. It is often used when talking about specific qualities, skills, or items that are needed. "Need of" is more general and can be used to refer to a wider range of things, including more abstract or less specific needs.
