load (n.) Look up load at Dictionary.com
c. 1200, lode, lade "that which is laid upon a person or beast, burden," a sense extension from Old English lad "a way, a course, a carrying; a street, watercourse; maintenance, support," from Proto-Germanic *laitho (source also of Old High German leita, German leite, Old Norse leið "way, road, course"), from PIE root *leit- (2) "to go forth" (see lead (v.1)).

It seems to have expanded its range of senses in early Middle English, supplanting words based on lade (v.), to which it is not etymologically connected. The older senses went with the spelling lode (q.v.). The spelling is modern. Meaning "amount customarily loaded at one time" is from c. 1300; meaning "a quantity of strong drink taken" is from 1590s. Meaning "the charge of a firearm" is from 1690s.

Meaning "a great amount or number" (often loads) is from c.1600. Figurative sense of "burden weighing on the mind, heart, or soul" is first attested 1590s. Meaning "amount (of work, etc.) to be done by one person" is attested in compounds from 1939 (first was workload). Colloquial loads "lots, heaps" is attested from c. 1600.

loaf (n.) Look up loaf at Dictionary.com
late 13c., from Old English hlaf "portion of bread baked in a mass of definite form," from Proto-Germanic *khlaibuz, the common Germanic word for "bread" (source also of Old Norse hleifr, Swedish lev, Old Frisian hlef, Old High German hleib, German Laib, Gothic hlaifs "bread, loaf").

The Germanic root is of uncertain origin; it is perhaps connected to Old English hlifian "to raise higher, tower," on the notion of the bread rising as it bakes, but (according to OED) it is unclear whether "loaf" or "bread" is the original sense. It is disguised in lord and lady. Finnish leipä, Estonian leip, Old Church Slavonic chlebu, Lithuanian klepas probably are Germanic loan words.

Meaning "chopped meat shaped like a bread loaf" is attested from 1787. Figurative use of loaves and fishes to suggest religious profession for the sake of personal gain" is from John vi.26.
loaf (v.) Look up loaf at Dictionary.com
1835, American English, apparently a back-formation from the earlier-attested loafer (1830). Related: Loafed; loafing. The noun meaning "an act of loafing" is attested from 1855.
The term "loafing" is, of course, very vague. Its meaning, like that of its opposite, "work," depends largely on the user. The highly successful quarterback with an E in Greek is a loafer in his professor's eyes, while the idea of the professor's working, in spite of his voluminous researches on Mycenean Table Manners, would excite hoots of derision from the laborer that lays the drains before his study window. [Yale Literary Magazine, May 1908]
loafer (n.) Look up loafer at Dictionary.com
"idler, person who loafs," 1830, of uncertain origin, often regarded as a shortened variant of land loper (1795), a partial loan-translation of German Landläufer "vagabond," from Land "land" + Läufer "runner," from laufen "to run" (see leap (v.)). But OED finds this connection "not very probable." As a type of shoe for informal occasions, 1937. Related: Loafers. By coincidence Old English had hlaf-aeta "household servant," literally "loaf-eater;" one who eats the bread of his master, suggesting the Anglo-Saxons might have still felt the etymological sense of lord as "loaf-guard."
loam (n.) Look up loam at Dictionary.com

The Norse word also is cognate with Old English læn "gift," which according to OED did not survive into Middle English, but its derived verb lænan is the source of lend (v.). From early 15c. as "a contribution to public finances" (ostensibly voluntary but often coerced; sometimes repaid, sometimes not). As a verb, loan is attested from 1540s, perhaps earlier, and formerly was current, but it has now been supplanted in England by lend, though it survives in American English.

And niðful neddre, loð an liðer, sal gliden on hise brest neðer [Middle English Genesis and Exodus, c. 1250]
Weakened meaning "averse, disinclined" is attested from late 14c. "Rare in 17th and 18th cents.; revived in the 19th c. as a literary word" [OED]. Loath to depart, a line from some long-forgotten song, is recorded since 1580s as a generic term expressive of any tune played at farewells, the sailing of a ship, etc. French laid, Italian laido "ugly" are from the same Germanic source.

lobster (n.) Look up lobster at Dictionary.com
large, long-tailed, stalk-eyed, 10-legged marine shellfish (Homarus vulgaris), early Middle English lopster, lopister, from Old English loppestre "lobster," also "locust," a corruption of Latin locusta, lucusta "locust, grasshopper," which is of unknown origin. De Vaan writes that "The only word similar in form and meaning is lacerta 'lizard; mackerel', but there is no common preform in sight. ... [T]hey could be cognate words in the language from which Latin borrowed these forms."

The change of Latin -c- to English -p- (and, from late 14c., to -b-) is unexplained; perhaps it is by influence of Old English loppe, lobbe "spider." The ending seems to have been altered by the old fem. agent noun suffix (preserved in Baxter, Webster, etc.; see -ster), which approximated the sound of Latin -sta.

OED says the Latin word originally meant "lobster or some similar crustacean, the application to the locust being suggested by the resemblance in shape." Trilobite fossils in Worcestershire limestone quarries were known colloquially as locusts, which seems to have been the generic word for "unidentified arthropod" (as apple was for "foreign fruit"). Locusta in the sense "lobster" also appears in Old Cornish legast and French langouste (12c.), now "crawfish, crayfish," but in Old French both "lobster" and "locust" (a 13c. psalter has God giving over the crops of Egypt to the langoustes).

As slang for "a British soldier" since 1640s, originally in reference to the jointed armor of the Roundhead cuirassiers, later (1660) to the red coat, the color of a boiled lobster.
Sir William Waller having received from London [in June 1643] a fresh regiment of five hundred horse, under the command of sir Arthur Haslerigge, which were so prodigiously armed that they were called by the other side the regiment of lobsters, because of their bright iron shells with which they were covered, being perfect curasseers.
