What is the difference between "conduct" and "operate" and "carry out" and "implement"? I have a question with the different usage of these four words. It seems they all have the intended meaning of "working in a certain way". Please help me to distinguish them.
The only verb that means "working in a certain way" is operate; the other verbs have different meanings.
For example, implement means "to make something that has been officially decided start to happen or be used."
A new work programme for young people will be implemented.
The regulations implement a 1954 treaty.
When speaking of code, I could say "I will implement the new program features over the next week."
As phrasal verb, carry out means "to do something that you have said you will do or have been asked to do" or "to do and complete a task."
Conduct - to behave in a certain way. Usually used reflexively, e.g. "Conduct yourself in a professional manner."
Operate - to use a machine or large tool correctly. This word will be used when A) using the machine or tool could be considered a skill by itself and/or B) the machine is somehow driven by gas, electricity, or non-human power. You wouldn't operate a canoe, but you might operate a motorboat.
Carry out - to do what is needed to make sure that something that is part of a plan happens. Carry out can also apply to responding to direct orders or requests.
Implement - to apply a method or principle to a process or part of a process. Implement is also a programming term that means to apply an algorithm.
