The word "deathwatches" may seem like it should be spelled differently, given its pronunciation. But when broken down phonetically, it makes sense. The first syllable, "death," is pronounced /dɛθ/. The second syllable, "watch," is pronounced /wɒtʃ/. And the plural "-es" is pronounced /ɪz/. So altogether, it's spelled "deathwatches" /dɛθˈwɒtʃɪz/. Though the word may not be commonly heard, it refers to the ticking sound made by a type of beetle, which was thought to be an omen of death in some cultures.
Deathwatches refer to a group of wood-boring beetles belonging to the family Anobiidae, specifically the subfamily Ptininae. This term is commonly used to describe the auditory activity of certain species of beetles that produce a ticking or tapping sound, traditionally believed to be an omen of impending death. The name "deathwatch" derives from the historical association of these sounds with the vigil or watch kept over a dying or deceased person.
These beetles are typically small, ranging from 2 to 7 millimeters in length, and are known for infesting wood, especially in old houses and structures where the wood has become decayed or softened. Their life cycle involves laying eggs within the wood, and the larvae feed on the cellulose fibers, creating tunnels as they burrow through the material. The tapping or ticking sounds emitted by deathwatches are produced by the insects' habit of knocking their heads against the walls of their tunnels as a form of communication, often linked to mating or territorial disputes.
Although deathwatches are generally considered harmless and do not pose any direct threat to humans or animals, their presence in buildings can be an indicator of underlying structural issues or rot in the wood. Therefore, their detection is of importance for homeowners and property managers as it can signify potential damage or decay that may require remediation.
The word "deathwatch" has an interesting etymology. It originated from the Middle English term "dethwakke" or "dethewak", which was a literal translation of the Old English word "dēaðwæcce". The Old English term combined "dēað" (death) and "wæcce" (watch, vigil).
This Old English word, in turn, was derived from the Germanic languages. The "dēaðwæcce" was closely related to the Old Germanic term "dauþawakō". Both of these terms were composed of "dauþa" or "dēað" (death) and "wakō" or "wæcce" (watch, vigil).
