One Word Substitution

Edible means fit for consumption by humans. Inedible means not fit to eat, unpalatable means unpleasant to taste, and eject means to throw out. The question directly asks for the word meaning fit to be eaten.

Emigrant means a person who leaves their own country to settle permanently in another. Import means to bring goods in, expatriate means living outside one's native country, and deport means to force someone to leave a country. The key distinction is emigrant refers to the person leaving.

Migrate means to move from one country or region to another, whether permanently or temporarily. Tariff is a tax, intromit is an uncommon word, and expat refers to a person living outside their native country. Migrate is the general verb for movement between countries.

Tariff is a tax or duty to be paid on a particular class of imports or exports. Literate means able to read and write, ineligible means not qualified, and budget is an financial plan. Tariff specifically applies to trade duties.

Repatriate means to send someone back to their own country. Invisible means cannot be seen, inaudible means cannot be heard, and exile means being sent away from one's country (not necessarily back to their own). Repatriate specifically refers to returning to one's homeland.

 A fortress that is impregnable is something that cannot be taken by force.

Irreparable means something that cannot be repaired or fixed. Inimitable means unique or unable to be copied, ineffaceable means cannot be erased, and ingrained means deeply fixed. The prefix 'ir-' means 'not' - not repairable.

Incorrigible means incapable of being corrected, reformed, or improved - typically describing someone with bad habits. Inevitable means unavoidable, irrelevant means not related, and curable means treatable. Incorrigible implies a permanent unwillingness or inability to change.

Indelible means marks or impressions that cannot be removed, erased, or washed away. The prefix 'in-' means 'not' and 'delible' comes from the Latin 'delere' (to erase). Inimitable means unique/uncopyable, infallible means incapable of making mistakes, and eradicable means can be removed (the opposite of what we need).

 Impervious means that it cannot be penetrated or is watertight and therefore is the correct answer.

Immortal describes something that lives forever or never dies. The 'im-' prefix negates 'mortal' (subject to death). Invisible means cannot be seen, immovable means cannot be moved, and immobile means not mobile or stationary.

A thermometer is specifically designed to measure temperature, using principles like thermal expansion of mercury or electrical resistance. The prefix 'thermo-' relates to heat. Barometers measure atmospheric pressure, telescopes magnify distant objects, and pyrometers measure very high temperatures in industrial contexts.

A microscope uses lenses to magnify tiny objects that are invisible to the naked eye. 'Micro-' means small and '-scope' means viewing instrument. Telescopes view distant objects, periscopes see around barriers (submarines, trenches), and prisms refract light into spectra.

A microphone converts sound waves into electrical signals that can be amplified, effectively increasing voice volume. The 'micro-' prefix indicates it works with small sound waves. Telephones transmit sound over distance, periscopes are optical viewing devices, and gramophones reproduce recorded audio.

A seismograph detects and records ground movements during earthquakes, creating a seismogram. The Greek root 'seismos' means earthquake or shaking. Dosimeters track radiation exposure, ammeters measure electrical current, and altimeters determine altitude above sea level.

An ammeter is an electrical instrument that measures current in amperes, its name a contraction of 'ampere meter'. Pentameter refers to poetic meter with five feet, speedometers measure velocity, and anemometers gauge wind speed.

A manometer measures pressure of liquids and gases using fluid columns or electronic sensors. The Greek 'mano-' refers to pressure (related to 'thin' or 'rarefied'). Micrometers gauge tiny distances, algometers measure pain sensitivity, and tensimeters assess surface tension.

Inevitable describes something certain to happen and impossible to prevent or avoid. The prefix 'in-' negates 'evitable' (avoidable). Impervious means impenetrable by water or other substances, avertable is the direct opposite (can be avoided), and crabbed means ill-tempered or grouchy.

Patriotism is the devotion, love, and attachment to one's country and its interests. An emigrant is someone who leaves their native country, 'national' is simply an adjective relating to a nation, and 'native' refers to birthplace rather than emotional attachment to country.

Amnesia is the partial or total loss of memory, often resulting from injury, illness, or psychological trauma. The Greek 'a-' prefix negates 'mnesia' (memory). Mnemonics are memory aids, panacea means a cure-all for diseases, and alexia is the inability to read (acquired dyslexia).

Acrophobia is the extreme or irrational fear of heights, derived from Greek 'akron' (summit, peak, or tip) and 'phobos' (fear). Ablutophobia is the fear of bathing or washing, aerophobia is the fear of flying (aviation), and agyrophobia is the fear of crossing streets or roads.

Audible literally means capable of being heard. Inaudible is the opposite (cannot be heard), Migrate means to move from one place to another, and Obscure means unclear or not easily understood.

Invincible means too strong to be defeated or conquered. Impassable refers to routes that cannot be traveled, Ordained means decreed by fate or authority, and Inexorable means unyielding or relentless.

Illegible means not clear enough to be read or deciphered. Literate means able to read and write, while Clear and Plain are antonyms - they describe writing that IS easy to read.

Legible means clear enough to read or decipher. Pleasing means agreeable, Savoury means appetizing (used for food/taste), and Ineligible means not qualified - none relate to readability.
