A one-name study is a project researching a specific surname, as opposed to a particular pedigree (ancestors of one person) or descendancy (descendants of one person or couple).
 Some people who research a specific surname may restrict their research geographically and chronologically, perhaps to one country and time period, while others may collect all occurrences world-wide for all time.

A concurrent estate or co-tenancy is a concept in property law which describes the various ways in which property is owned by more than one person at a time.
 If more than one person owns the same property, they are referred to as co-owners.
 If more than one person leases the same property, they are called co-tenants or joint tenants.
 Most common law jurisdictions recognize tenancies in common and joint tenancies, and some also recognize tenancies by the entirety.
 Many jurisdictions refer to a joint tenancy as a joint tenancy with right of survivorship, and a few U.S. states treat the phrase joint tenancy as synonymous with a tenancy in common.
Triangulation is a manipulation tactic where one person will not communicate directly with another person, instead using a third person to relay communication to the second, thus forming a triangle.
 It is also a form of splitting in which one person manipulates a relationship between two parties by controlling communication between them.
Radar Station is a 1953 Canadian short documentary film produced by the National Film Board of Canada (NFB) as part of the "On The Spot" series made specifically for television.

Taqlid or taqleed (Arabic تَقْليد "taqlīd") is an Islamic terminology denoting the conformity of one person to the teaching of another.
 The person who performs taqlid is termed "muqallid".
 The definite meaning of the term varies depending on context and age.
 Classical usage of the term differs between Sunni Islam and Shia Islam.
 Sunni Islamic usage designates the unjustified conformity of one person to the teaching of another, apart from justified conformity of layperson to the teaching of "mujtahid" (a person who is qualified for independent reasoning).
 Shia Islamic usage designates the general conformity of non-mujtahid to the teaching of mujitahid, and there is no negative connotation.
 In contemporary usage, especially in the context of Islamic reformism, it is often shed in a negative light, and translated as "blind imitation".
 This refers to the perceived stagnation of independent intellectual effort ("ijtihad") and uncritical imitation of traditional religious interpretation by the religious establishment in general.
