What does lacertid mean?
A lacertid is a member of Lacertidae, the taxonomic family that includes the true lizards. This is the largest family of living lizards, containing hundreds of species distributed mainly across Europe, Africa, and western Asia. The group includes familiar animals such as the sand lizard, common lizard, and green lizard, as well as many less conspicuous species. The word is especially useful in zoology, ecology, and conservation, where identifying an animal only as a lizard would be too broad. Although most living lizard species are lacertids, several prominent groups, including geckos, chameleons, iguanas, skinks, and monitor lizards, belong to different families. As an adjective, lacertid describes characteristics belonging to or associated with this family.
A lizard belonging to the family Lacertidae.
"The biologist recognized the animal as a lacertid rather than a gecko."
A taxonomic term used especially in zoological, ecological, and evolutionary contexts.
Relating to or characteristic of a member of the family Lacertidae.

Usually used in scientific or natural-history writing.
The standard plural is lacertids, used when referring to several members of the family.
"Several lacertids shelter beneath flat stones during the heat of the day."
Most lizards are lacertids, but not every lizard is: geckos, chameleons, iguanas, and monitor lizards belong to other families.
