In crystallography, a crystal system is a set of point groups (a group of geometric symmetries with at least one fixed point). A lattice system is a set of Bravais lattices. Space groups are classified into crystal systems according to their point groups, and into lattice systems according to their Bravais lattices. Crystal systems that have space groups assigned to a common lattice system are combined into a crystal family.
The seven crystal systems are triclinic, monoclinic, orthorhombic, tetragonal, trigonal, hexagonal, and cubic. Informally, two crystals are in the same crystal system if they have similar symmetries (albeit there are many exceptions).

I THINK CRYSTAL IS THE NAME OF A GIRL. UNNIE IS THE KOREAN WORD THAT MEANS OLDER / ELDER SISTER . SO THE ANSWER WILL BE :-
I SAID ( TOLD ) TO MY ELDER ( OLDER ) SISTER , " CRYSTAL SIS PLEASE ANSWER AGAIN , BECAUSE YOUR ANSWER WAS DELETED ( REMOVED ) ALREADY. "
I HOPE IT WILL CORRECT ☺️ MY DEAR OPPA ..........
