A trail is usually a path, track or unpaved lane or road, though the term is also applied, in North America, to routes along rivers, and sometimes to highways. In the United Kingdom and the Republic of Ireland path or footpath is the preferred term for a walking trail. Some trails are single use and can only be used for walking, cycling, horse riding, snow shoeing, cross-country skiing, etc., others, as in the case of a bridleway in the UK, are multi-use, and can be used by walkers, cyclists and equestrians.
There are also unpaved trails used by dirt bikes and other off road vehicles. In some places, like the Alps, trails are used for moving cattle and other livestock (see transhumance). In the US historically, the term was used for a route into or through wild territory used by emigrants (e.g. the Oregon Trail).
In Australia, the term track can be used interchangeably with trail, and can refer to anything from a dirt road to an unpaved pedestrian path. The term trail gained popularity during World War II, when many servicemen from the United States were stationed in Australia, which probably influenced its being adopted by elements of the Australian media at the time (see Kokoda Track).

Trail is a competitive class at horse shows where horses and riders in western-style attire and horse tack navigate a series of obstacles. Contestants ride the course one at a time. Originally designed to resemble situations a horse and rider might actually encounter when on a trail in a natural habitat, modern trail classes now tend to focus more heavily on agility and manners, with courses bearing very little resemblance to real-world natural trails.
A typical trail course requires horse and rider to open and pass through a small gate while mounted; walk across a fake bridge; cross over a set of rails or logs at a walk, trot or lope; back up, often with a turn while backing; sidepass, often over a rail or log; turn on the forehand or hindquarters within a confined area; and tolerate some type of "spooky" obstacle, such as having the rider put on a vinyl raincoat. The horse is asked to perform all three gaits in the process of completing the course.
Additional obstacles or tests may include walking over a plastic tarp or through water; having the horse ground-tie (remain standing in one spot while the rider walks away); to walk, trot or lope in very tight quarters, such as traveling through a series of cones or markers in a serpentine pattern; or take a small jump (usually under 18 inches, as riders are in western saddles and cannot easily get off the horse's back into a jumping position).
In linguistics, a numeral is a member of a word class (or sometimes even a part of speech) designating numbers, such as the English word 'two' and the compound 'seventy-seven'.
Numerals may be attributive, as in two dogs, or pronominal, as in I saw two (of them).
Many words of different parts of speech indicate number or quantity. Quantifiers do not enumerate, or designate a specific number, but give another, often less specific, indication of amount. Examples are words such as every, most, least, some, etc. There are also number words which enumerate but are not a distinct part of speech, such as 'dozen', which is a noun, 'first', which is an adjective, or 'twice', which is an adverb. Numerals enumerate, but in addition have distinct grammatical behavior: when a numeral modifies a noun, it may replace the article: the/some dogs played in the park → twelve dogs played in the park. (Note that *dozen dogs played in the park is not grammatical, so 'dozen' is not a numeral.)
