Elderly care or elder care is a broad term encompassing such services as assisted living, adult day care, long term care, nursing homes, hospice care, and Alzheimer's care.

Regardless of purpose, however, the term fishery generally refers to a fishing effort centered on either a particular ecoregion or a particular species or type of fish or aquatic animal, and usually fisheries are differentiated by both criteria. Examples would be the salmon fishery of Alaska, the cod fishery off the Lofoten islands or the tuna fishery of the Eastern Pacific. Most fisheries are marine, rather than freshwater; most marine fisheries are based near the coast. This is not only because harvesting from relatively shallow waters is easier than in the open ocean, but also because fish are much more abundant near the coastal shelf, due to coastal upwelling and the abundance of nutrients available there.

Forensic science (often shortened to forensics) is the application of a broad spectrum of sciences to answer questions of interest to the legal system. This may be in relation to a crime or to a civil action. The use of the term forensics in place of forensic science could be considered incorrect; the term forensic is effectively a synonym for legal or related to courts (from Latin, it means before the forum). However, it is now so closely associated with the scientific field that many dictionaries include the meaning given here.
