This word refers to the special language a family or group of children would use to communicate with each other.

I thought it was sartorial, but that is about clothing choices or tailoring.

It was used to describe a large family's special language that others could not easily understand. For example in my family we used the word plogged up to describe a clogged or plugged drain and the like.

The most relevant and appropriate word has a syllabic rhyming similarity (which may explain your confusion) to your first thought of “sartorial”. It is argot.

words and expressions that are used by small groups of people and that are not easily understood by other people

Another weaker possibility might be jargon, which also has the rhyming similarity, but usage and the definition associate this word with work groups rather than other groups.

special words and phrases that are used by particular groups of people, especially in their work

  • I believe lingo is even more appropriate for the jargon of small groups but their use is inconsistent. Dictionary.com definition: "the language and speech, especially the jargon, slang, or argot, of a particular field, group, or individual". Argot is usually used as a secret language to exclude outsiders.
