Klingon has two distinct ways to express the idea of "between," depending on what exactly is meant. Each construction has a specific use based on whether you are referring to a point within a range or the entire span between two things.

1. A Point Between Two Limits

When "between A and B" refers to a point that lies somewhere in the range defined by A and B (but not necessarily at either end), Klingon uses:

rav A 'aqroS B

Here, rav means "minimum" and 'aqroS means "maximum." This construction is often used for measurements or ranges.

• rav cha' 'uj(mey) 'aqroS loS 'uj(mey) 'ab
  It has a length between two and four uj (it is at least two uj long and no more than four).
• rav DaSjaj 'aqroS buqjaj maghom
  We meet at some point between Monday and Friday.

2. The Full Span Between Two Points

When "between A and B" refers to the entire span from A to B — such as a continuous stretch of time, distance, or activity — Klingon uses the noun qubbID ("span" or "interval").

• DaSjaj buqjaj (je) qubbID maleng
  We travel between Monday and Friday. (We travel the whole span from Monday to Friday.)
• DaSjaj buqjaj (je) qubbID maghom
  We meet between Monday and Friday. (We meet sometime during that span.)

So, to summarize:

• Use rav... 'aqroS... for a location or moment within a range.
• Use qubbID for the entire span from one point to another.
