Is there an s after the + thread after the number (such as: 1.2.3.4.5.6…………)?

When numbers are followed by thousand without s, unless it is used to describe "thousands and thousands" or "thousands", thousands is followed by + of, ----thousands of, which is a fixed combination. means thousands.

Just + adjective after very, cloudy, rainy, windy.

I didn’t understand the original poster’s meaning in the second question
