English term or phrase: tortoise vs. turtle
What is the difference between the two terms? I thought that a 'tortoise' is a terrestrial animal whereas a 'turtle' lives in the sea. However, in case of the European pond turtle/tortoise (Emys orbicularis) both names or used (as St. Google says), also by UK sources. And there is a terrible 'terrapin' as well ...

the different names might be due to etymology:

TORTOISE:
Etymology:Middle English tortuce, tortous, tortuse, probably alteration (the gen. being taken as the noun attrib.) of tortu, from Middle French tortue

TURTLE:
Etymology:probably by folk etymology (influence of 1turtle) from French tortue, probably from (assumed) Vulgar Latin tartaruca, from Late Latin tartarucha, feminine of tartaruchus of Tartarus, from Greek tartarouchos, from Tartaros Tartarus, the infernal regions; from the turtle\'s having been regarded in ancient times as an infernal creature

Explanation:
Turtle, Tortoise, and Terrapin: What’s the Difference?
All turtles, tortoises, and terrapins are reptiles. Scientists often refer to them as chelonians, because they are in the taxonomic order called Chelonia (from the Greek word for tortoise). They all have scales, lay eggs, and are ectothermic. So why the different names? Those common names usually refer to differences in where the species live and how they use their habitat. But the names are also used differently in other parts of the world. For instance, in Australia only sea turtles are called turtles–everything else is called a tortoise! But here are some generally accepted differences between the types of chelonians.

Tortoises and turtles
Tortoises and turtles are reptiles belonging to the order Cheonia (or the order Testudines, according to some classification systems). Tortoises and turtles are unique reptiles, having a shell that is a modified structure formed from their ribcage and vertebral column.

agree  Richard Benham: In Australia, turtles have flippers, tortoises feet. But I understand (from a sign in the Adelaide Zoo) that "turt;le" in its broader sense includes tortoises.

Explanation:
Turtle : any marine (+ terrestrial in the US) reptile of the order Chelonia

Tortoise: any marine or terrestrial chelonian from the Testudinidae family

I understand that all tortoises are turtles, though all turtles are not tortoises.

An order includes several families
