Does the word "concurrent" imply only two conditions?

If I wanted to imply that at any given time I'm managing many projects of different durations that overlap, is it redundant to say "I manage multiple concurrent projects"? Does "numerous concurrent" sound less ridiculous?

Solution 1:

Neither Lexico nor Chambers confines the use of concurrent to only two simultaneous events or processes. Indeed the first example at Lexico is

there are three concurrent art fairs around the city

while Chambers defines the word to mean

running, coming, acting or existing together or simultaneously.

It's a mite redundant to include the word concurrent in your sentence I manage multiple concurrent projects, I think the use of manage in the present tense implies that you manage them at the same, current, time. But it's a small nit to pick at and I wouldn't have thought twice about it if your question hadn't raised the issue.

And on the axis of ridiculosity numerous concurrent scores higher than multiple concurrent, ie is more ridiculous to this reader.
