I have just encounter with the explanation in a site. I am wondering if it is right and if you could give a vivid example to clarify it better.
Involvement does not suggest requirement. You can be part of something without being required for it.that is the difference.
Could we use involve instead require but we couldn’t use require instead of involve?
Thanks in advance
Need for a particular purpose:
three patients required operations
Have or include (something) as a necessary or integral part or result:
my job involves a lot of travelling
You understood correctly: to require is to need while to involve is to imply that something is part or result of.
