Request to get the pluralize filter implimented into Treepl.
{% assign itemCount = "3" %}
{{ itemCount | pluralize: 'item', 'items' }}
Output:
3 items
Example from: String filters
Also with the option to use variables ie:
{% assign term = "minute" %}
{% assign terms = "minutes" %}
{% assign time = 50 %}
{% assign prettyTimePlural = time | pluralize: term, terms %}
{% assign prettyTime = time | append: " " | append: prettyTimePlural %}
Output: {{ prettyTime }}
50 MinutesJust out of curiosity, why does the Shopify docs have a note about āEnglish pluralization rulesā when you set the singular and plural words in the filter yourself? you could have any 2 terms you like regardless of language.
Or can you use it on a word/string as well? ie:
{{ "day" | pluralize }}
Giving you:
days
Yeah that one struck me as odd as well. maybe there is some hidden functionality in the docs, that we donāt see?
If your example was a thing then i guess language would come into it.
I did find this reference which sheds a little more light on it:
Liquid Filters Ā· DocSpring Docs
The plural string isnāt required, so it defaults to adding an āsāā¦ I guess thatās all.
Anyhooā¦ I think I look into things too much 
This filter would be handy to have either way.
Oh that makes senseā¦ and then you can specify for cases like this when the spelling is different.
"city", "cities"
makes total senseā¦ ha
