The word "chinkers" typically refers to narrow gaps or openings in a building or structure that allow air or light to enter. Synonyms for this word include "cracks," "crevices," "fissures," and "gaps." Other related terms include "clefts," "creases," "hollows," and "apertures." These words all refer to narrow spaces in a structure or object that may allow for air or light to pass through, but can also pose a risk for water damage or other structural problems if left unfilled. Effective sealing or filling of chinkers is important for maintaining the integrity and overall condition of a building or structure.
