In one line
A conjunction — one of the ten linking particles (و، ف، ثُمَّ، أَوْ…) that make what follows share the case of what precedes.
The classical list
وَحُرُوفُ الْعَطْفِ عَشَرَةٌ وَهِيَ: الْوَاوُ، وَالْفَاءُ، وَثُمَّ، وَأَوْ، وَأَمْ، وَإِمَّا، وَبَلْ، وَلَا، وَلَكِنْ، وَحَتَّى فِي بَعْضِ الْمَوَاضِعِ.
“The conjunctions are ten: waw (and), fa (so/then), thumma (then, later), aw (or), am (or, in questions), imma (either), bal (rather), la (not), lakin (but), and hatta (even — in some contexts).”
Key words in the Arabic
ثُمَّthen — with a gap in time
بَلْrather — correcting course
فِي بَعْضِ الْمَوَاضِعِin some contexts only
Understand it

Each connector links — but each adds its own flavour: و joins without order, ف joins in immediate sequence, ثُمَّ after a pause, أَوْ offers choice, بَلْ corrects. The grammar is uniform (the ma'tuf copies the case); the meaning is where these ten differ, and Quranic reasoning often turns on exactly which one was chosen.

The ten hurūf al-'atf
#Meaning
1الْوَاوal-wāwand — simple joining, with no claim about order
2الْفَاءal-fā'and then — order, with no gap
3ثُمَّthummathen — order, with a gap
4حَتَّىhattāeven — a last item that is the extreme of what came before
5أَوْawor — a choice between them
6أَمْamor — the 'or' that belongs inside a question
7إِمَّاimmāeither — paired with another إِمَّا
8بَلْbalrather — dropping the first and affirming the second
9لَاnot — affirming the first and denying the second
10لَكِنْlākinbut — correcting, and only after a negative or a prohibition

Whatever the meaning, the grammar is one rule: the word after the particle takes the same i'rab as the word before it. That is what makes 'atf so useful when reading — the ending you already worked out carries straight over.

How to spot it
Recognition test
A small linker between two words of matching case, or two clauses — a harf 'atf.
In the Qur'an
ٱلشَّمْسُ وَٱلْقَمَرُ بِحُسْبَانٍ
Ar-Rahman 55:5 — “The sun and the moon follow courses (exactly) computed;”
وَٱلْقَمَرُ is joined on by its waw to ٱلشَّمْسُ before it, and copies its rafa. That is the whole job of a harf 'atf: it links, and what follows takes the same i'rab as what came first.

Common questions

Do all ten linking particles mean the same thing?

No — only their grammar is shared. Each one carries its own sense: simple addition, immediate sequence, delayed sequence, choice, correction. What they have in common is that whatever follows takes the same i'rab as whatever came before.
