Reference specific sentence as claim

Question

I know that there have been some similar questions, but in neither did I find any answer that can work for me.

I'm writing a philosophy paper, and want to reference claim I make as I write in a numbered manner, similar to how you would reference theorems, claims, or equations in a math paper.

The setting would be something like this:

This is a paragraph I'm writing, and {here is a claim I'd like to reference} \label{clm:claim1}
...
Some other paragraph I'm writing, and I reference \ref{clm:claim1}.

In the \ref{clm:claim1} I want instead to either appear (I), (1), or Claim 1

Can anyone give me pointers on how to do this? I'm using Overleaf with XeLatex.

Thanks!

You can have LaTeX allocate a new counter whose name is NewCounter for counting whatever things via \newcounter{NewCounter}[<name of superordinate counter whose incrementing will reset NewCounter to the value 0>].
You can have LaTeX increment the counter NewCounter via \stepcounter{NewCounter} and via \refstepcounter{NewCounter}.
When you use \refstepcounter, then it is possible to place a command \label{MyLabel} somewhere between that \refstepcounter-directive and the next \refstepcounter-directive. When you do that, then

• you can via \pageref{MyLabel} reference the number of the page which LaTeX was about to construct when encountering the \refstepcounter-directive
• you can via \ref{MyLabel} obtain those things which you could obtain via \p@NewCounter\theNewCounter at the time right after LaTeX carried out the \refstepcounter-directive. (\p@NewCounter is intended to provide a standard-prefix which will be prepended to each reference via \ref. Usually \p@-macros are defined empty.)

Be aware that all this referencing is possible even when the value of NewCounter was never printed via \theNewCounter after "refstepping" NewCounter.

When the hyperref-package is loaded, then

• \refstepcounter will also trigger placing a destination/an anchor into the .pdf-file whose name is derived from the value of NewCounter by means of the macro \theHNewCounter.
• \ref/\pageref do not only deliver textual phrases but will deliver the textual phrases turned into hyperlinks which can be clicked for scrolling/navigating to that section of the document which is referenced.
• you can use \hyperref[<name of referencing-label>]{<custom phrase>} in order to obtain customized phrases turned into hyperlinks which can be clicked for scrolling/navigating to that section of the document. Within the <custom phrase>-argument you can use the starred variants \ref*/\pageref*.

You wrote,

I'm writing a philosophy paper, and want to reference claim[s] I make as I write in a numbered manner, similar to how you would reference theorems, claims, or equations in a math paper.

The amsthm and ntheorem packages can be used to create numbered theorem-like environments. These environments needn't be theorems, lemmas, corollaries in the usual mathematical sense; they can be "claims" too. The following code shows how to (a) set up an environment called claim and (b) how to cross-reference instances of this environment via the usual \label-\ref mechanism.

\documentclass{article}
\usepackage{lipsum}
\usepackage{amsthm} % for \theoremstyle and \newtheorem macros
\usepackage[colorlinks,allcolors=blue]{hyperref} % optional
\usepackage[nameinlink]{cleveref}

\theoremstyle{definition} % for a non-flashy, even somewhat subdued 'look'
\newtheorem{claim}{Claim}
\renewcommand\theclaim{(\Roman{claim})} % set as needed
\crefname{claim}{Claim}{Claims}


\begin{document}

\lipsum[1-2] % filler text

\begin{claim}\label{clm:claimX}
Here is a claim I'd like to reference.
\end{claim} 

\lipsum[3-6] % more filler text

Some other paragraph I'm writing, in which I cross-reference \cref{clm:claimX}. 

\end{document}
