I'm trying to think of a word that basically communicates something in between a single and a double.

Is there such a thing as half of a tuple?

How would you communicate something that is in between a single and a double?

  • You're not, but you kinda are... If you tied two ropes together with a double overhand, you're essentially left with a knot with four loops. A single overhand would be two loops. The knot I'm tying has three loops... I'm tying a single with one strand, then a double with the other, but in "knot math" that does not add up to a triple, it's one single less that a double... but not a single... I need help.

    @tchrist, this isn't a duplicate, that question is about Ordinal Numbers, this one is about Tuples.

There is a Latinate prefix, sesqui-, for 'one and a half', which is occasionally used for terms like sesquicentenary. How you adapt this to your very specific situation (and whether it will mean anything to anyone else when you do so) is up to you.

    I was able to discover that Sesquidupal was a word which means two and a half, but I can't find a series of tuple and a half words.

  • @ShemSeger: I think the word for one and a half would be "sesquuple"

  • Wikipedia indicates that various Latin roots are used with the "uple" endings. Unfortunately, there seems to be no Greek equivalent to "sesqui-": en.wikipedia.org/wiki/Numeral_prefix

I'd say half-double. Refer to crochet terms.

    Because it's only half doubled haha. One half double is half the increase a double would be, so 50% more

Half of double is single. If you're talking about a quantity rather than groups of integral units, you can say "one and a half."
