Surface Forms

chroot singular
chroots plural

Morphology

chroot = root (semi-transparent) = ch + root

The element 'root' directly relates to filesystem root, but 'ch' is an abbreviation/clipping of 'change' used in technical jargon and is not transparently interpretable to typical learners.

Etymology

Chroot comes from ch- (short for 'change') and root (the 'top' directory of a computer). It started as a Unix command to 'change root' for a process, and the name tells you its job: to move a program into a separate root so it cannot affect the rest of the system.
