Note
A different word again, from Middle French railler, and today it takes a preposition. Nelson Mandela's chief 'railed against the white man', Saki's Major railed 'at fate', and Mark Twain writes 'let them rail on'. Shakespeare could still give it a direct object in The Merchant of Venice: 'Till thou canst raile the seale from off my bond.'

- 5In an electrical circuit, a conductor held at a constant voltage with respect to ground, serving as a common connection for other components.
Each amplifier stage connects between the supply rail and ground.
Noise on the power rail can disrupt sensitive measurements.
Note
Electronics names each rail by its voltage: a power supply has +12 V, +5 V and 3.3 V rails, and negative ones such as −12 V. 'The 12V rail' is shorthand for everything held at that potential. Michal Necasek's 'Power Trouble' (2019) traces how PC power supplies shifted load from the 5V and 3.3V rails toward 12V because it is more efficient.

- 6Either of the two vertical side bars of a ladder into which the rungs are fixed.
He wiped the paint off the left rail before folding the ladder away.
The ladder's rails were made of lightweight aluminum.
Note
Ladder rails come in pairs, with the rungs fixed between them, and the part has two other names: stile and stringer both mean this upright side bar. Notice the change of direction. Here the bar stands vertical, while the barrier rail runs horizontally.

Note

- 8Any of several marsh-dwelling birds of the family Rallidae, typically with short rounded wings and long toes for walking on soft ground.
The birdwatcher finally glimpsed a rail slipping through the dense marsh grass.
Several rails nested in the wetland that spring.
Note
The bird's name is a separate word, borrowed from French râle and named for the bird's harsh cry. Its root is Latin rādere, 'to scrape', so the name is a sound picture of a scraping call. It has no connection with bars or railways. Medieval Latin rallus is the same name, and it lives on in the family name Rallidae.

Similarline
Note
Drug slang in which size is the point: a rail is a line laid out large. It counts like any ordinary noun (a fat rail, a couple rails), and Jason Isbell's song 'Super 8' (2013) uses it in exactly that way. The same image lies behind the verb for snorting a line, where you rail a line rather than do one.

Note
The verb that goes with the noun for a big line: to rail is to take that line in one snort. It is transitive, and its object can be the drug or the line itself, as in Tommy Dorfman's Maybe This Will Save Me (2025): "desperate to rail a line of blow."

- 12To set a railway vehicle onto the track.
Note
A railway workers' verb, and strictly transitive: its object is rolling stock, such as a wagon, a coach or a locomotive, set onto the running rails so the wheels sit on the track. It is the mechanical side of the verb and has little to do with traveling by train, which takes no object at all.

- 14The raised border running around the edge of a game board, especially in backgammon.
Her die bounced off the rail and rolled to a stop near the middle of the board.
The dice bounced off the rail of the backgammon board and rolled onto the floor.
Note
Backgammon's border matters most as a boundary for the dice. A throw counts only when both dice come to rest flat inside the board, not cocked against or on top of the rail. The edge is part of the rules as well as the furniture, and players watch it on every roll.
Checked 1 Nov 2026 · 2 facts

- Dice cocked against the rail or resting on top of it do not constitute a valid throw; the border therefore affects the rules. usbgf.org
- 15A garment, such as a cloak or dress.
Note
This is a different word from the bar and the railway, though the spelling is the same. It comes from Old English hræġl, meaning "garment, dress, robe," and has relatives in Old Frisian hreil and Old High German hregil. Because it is obsolete, it belongs to the reading of older texts or to deliberate period color, never to plain modern speech. The headscarf meaning narrows it to a single item of a woman's dress.

- 16A woman's headscarf or neckerchief.
A course hempen raile about her shoulders.
1592, Thomas Nashe, Pierce PennilessNote
The general 'garment' sense narrowed to one item a woman wore at the head or neck. Thomas Nashe's Pierce Penniless (1592) puts 'a course hempen raile about her shoulders'. That rail is made of coarse hemp, which suggests ordinary cloth rather than finery. The spelling raile is the one to look for in texts of that period.

his breste and his brayle was bloodé – and hit rayled all over the see.
1470, Thomas Malory, “Capitulum iv”Note
An obsolete verb of uncertain origin, probably from Anglo-Norman raier, and in Malory and Spenser it runs with blood. Malory's Le Morte Darthur has blood that 'rayled all over the see'. Spenser's Faerie Queene (1596) has 'streames of bloud' that 'rayle adowne'. Readers of older verse meet it as rayle, and it has no link to the railway words.

The wind's counterpart to the obsolete 'gushing' verb, from the same probable source. It applied to moving air what that verb applied to moving liquid. It is obsolete and was used only of wind. A modern reader who meets wind that 'rails' in an older text should read it as blowing, not complaining.

Origins
Latin "regō" (to rule, guide, govern) gave "regula" (rule, bar), and this reached English by two paths: Old English "regol," meaning a ruler or straight bar, and Old French "reille." Together they produced Middle English rail. Regal, rule, and several other words are doublets.
The bird is named for its harsh cry. The name traces from Latin "rādere" (to scrape) through Vulgar Latin "*rasculum" to Old French "rasle," Middle French "raalle," and finally French "râle."
From Middle French "railler".
