Pronunciation: [sˈe͡ɪlɛs] (IPA) 
Sailless is spelled with three syllables: /ˈseɪl.ləs/. The first syllable "sail" is pronounced like the word for the canvas structure that catches wind to propel a boat forward, and the second syllable is pronounced like "less". Sailless means "without sails" and is commonly used to describe a boat that is not equipped with sails or to describe a time when there is no wind to power a sailing vessel.
Sailless refers to something or someone that is devoid or lacking in sails. The term sailless is derived from the word "sail," which typically denotes a large piece of fabric attached to a mast or spar that utilizes the force of wind to propel boats, ships, or other watercraft across the water.
In the literal sense, "sailless" is often used to describe boats or vessels that do not possess sails and therefore rely on alternative means of propulsion, such as engines or oars. These sailless vessels are typically powered by various mechanical methods, including combustion engines or electric motors, which allow them to move efficiently through the water.
Beyond its literal definition, sailless can also be used metaphorically to describe a lack of direction or purpose. In this sense, sailless suggests the absence or absence of guiding principles or goals, leaving someone or something adrift without a clear course of action. This metaphorical usage implies a sense of aimlessness or confusion, as if unable to make progress due to a lack of guidance or motivation.
Overall, sailless typically conveys the idea of something being without sails, whether in the literal sense referring to boats or ships, or in the metaphorical sense of being directionless or lacking purpose.
Without a sail.
Etymological and pronouncing dictionary of the English language. By Stormonth, James, Phelp, P. H. Published 1874.
The word "sailless" is formed by adding the suffix "-less" to the noun "sail".
The suffix "-less" in English is derived from the Old English suffix "-lēas", which originally meant "devoid of" or "lacking". It is related to the German "-los" and the Old Norse "-lauss". Over time, "-less" has become productive in English, allowing the formation of new words by adding it to various nouns, expressing the concept of "without" or "lacking".
In the case of "sailless", the suffix "-less" is appended to the noun "sail", which refers to a piece of fabric attached to a mast to catch the wind and propel a boat or ship. Thus, "sailless" means "without a sail" or "lacking a sail".
