Dear Orange,
Peace to you.
The Arabic word 'Hadith' means a report, tale, story, statement, narration, a communication or a discourse. Its plural form is 'Ahadith'. In common parlance, 'Hadith' has now become synonymous with a specific body of work within Islamic literature which constitutes narrations that depict the words and practices of the Prophet Muhammad (pbuh) and are attributed to him.
However, this is not the manner in which the Quran uses the term in the verse you have shared. Hadith can also mean conversation, talk depending on its usage in context. Please see verse 6:68.
"fa-arid anhum hatta yakhudu fi hadithin ghayrihi" - "Then turn away from them until they engage in a
talk / conversation other than it"
In the verse you have shared, please also note the prefix preposition lam, which is best rendered as 'for'. So 'li-hadithin' would better translate as 'for conversation / talk' in my humble opinion.
I hope that helps, God willing.
Joseph.
