Lieutenant is a military rank, the equivalent of which is used by the service organizations of many civilizations. As a traditional naval rank, lieutenant is the grade between ensign and lieutenant commander. In infantry, lieutenant is the lowest officer grade, falling below captain. An infantry lieutenant commands a platoon, consisting of about thirty troops.
In the Starfleet, the rank of lieutenant was directly between ensign and commander. The Federation Starfleet uses additional grades in this transition, lieutenant junior grade, lieutenant and lieutenant commander. This is identical to the system used by many older Earth agencies. Starfleet lieutenants are expected to be effective small-section leaders and technical experts, developing their leadership skills in preparation for promotion to the commander tier.
In old Earth terms (such as the United States armed forces), infantry lieutenants were divided as first lieutenant and second lieutenant, equivalent to naval ensigns and lieutenants junior grade.
In the Romulan Star Empire, there exists a lieutenant grade and also a lower grade, sublieutenant. In the old Earth English navy, the rank sublieutenant is equivalent to ensign.
The Andorian Imperial Guard in the 22nd century used the rank of lieutenant.
This grade presumably exists in some form in many other cultures' rank arrangements.
The German word for "lieutenant" is "Leutnant". The British pronunciation is "lef-tenant", as opposed to "loo-tenant". (TNG: "Tapestry", "Ship in a Bottle")
The New Sydney police bureau also used the rank. Fuchida was a lieutenant in 2375. (DS9: "Prodigal Daughter") Additionally, the New York City Police Department used the rank of lieutenant. Gary Seven had identification stating he was a lieutenant in the NYPD when he was sent to Earth in 1968. (TOS: "Assignment: Earth")
Many rank systems use the term lieutenant in front of other grades to create a lower grade, lieutenant colonel and lieutenant general for example.

Background
Since TNG: "The Defector" established that the Romulans have a sublieutenant rank, it seems suggests that there would be a regular lieutenant rank it was subordinate to.
