What does interstice mean?
An interstice is a small gap or space between two adjacent things. The word is especially useful when describing the narrow openings between bricks, roots, stones, beams, cells, or other tightly arranged elements. It suggests a space that is limited but perhaps significant, whether because something can pass through it, because it reveals a hidden detail, or because it affects the structure as a whole. In everyday speech, gap or opening is often sufficient, but interstice has a more precise, technical, and slightly literary tone. The term can also be used figuratively for small spaces or overlooked places within larger systems, though its principal modern meaning concerns physical intervals. It is the noun from which the adjective interstitial is commonly derived.

Where does interstice come from?
Interstice comes from Latin interstitium, a word formed from inter- (“between”) and stare (“to stand”), originally referring to a space between things that stand or are placed next to one another. English borrowed the Latin noun in the 17th century. The same Latin verbal root underlies related words such as station, status, and the English derivative interstitial, which describes something occurring in or occupying the spaces between other elements.

How interstice is actually used
The word is relatively uncommon and formal or technical. It is especially used for narrow gaps in physical structures, materials, and biological tissues; in ordinary speech, gap, opening, or crevice is usually more natural.
