Is it correct to refer to someone who is using something a lot, by 'a big user of ...'. I'm talking here specially about software usage.
Is there an accurate word ?


Yes, big can be used to describe a user who uses a program a lot.

1.5 - Doing a specified action very often or on a very large scale

A second choice could be frequent which would be a bit more formal.

1.1 - [attributive] (of a person) doing something often; habitual

A third choice could be heavy which, like big, would be a little less formal.

3.2 - Doing something more, or more deeply, than usual.

If the person is an expert in all functions of the program they may also be called a Super User (hence one of the most popular sites on SE being named that).

A user of a computer system with special privileges needed to administer and maintain the system

    A constant user. A regular user. – GEdgar Jan 22 '16 at 14:16

    'Frequent' is different from 'heavy'. If I use the system for 1 minute every day, I'm a 'frequent' user, but possibly not a 'heavy' user. (Assuming that most people use it less frequently.) If I use it for a whole day every month I might be a 'heavy' user but not a 'frequent' user. – DJClayworth Jan 22 '16 at 14:23
  • @GEdgar I think 'regular' is very close to the meaning of what I want to express. – elsadek Jan 22 '16 at 14:42

If someone is a 'big' user of something, it means they use it a lot. There isn't a specific frequency, or amount, of use that defines 'big', any more than there is a specific size that qualifies for the physical description 'big'.

  • What I'm looking for should be in professional context. – elsadek Jan 22 '16 at 14:11
  • Everything I wrote in this answer applies in a professional context. If you need to consider an amount that they use the system, then you have to specify that amount. – DJClayworth Jan 22 '16 at 14:21
