Middle Dutch in the context of Medieval Dutch literature

A dam is a barrier that stops or restricts the flow of surface water or underground streams. Reservoirs created by dams not only suppress floods but also provide water for activities such as irrigation, human consumption, industrial use, aquaculture, and navigability. Hydropower is often used in conjunction with dams to generate electricity. A dam can also be used to collect or store water which can be evenly distributed between locations. Dams generally serve the primary purpose of retaining water, while other structures such as floodgates or levees (also known as dikes) are used to manage or prevent water flow into specific land regions.

The word dam can be traced back to Middle English, and before that, from Middle Dutch, as seen in the names of many old cities, such as Amsterdam and Rotterdam.

Measles (probably from Middle Dutch or Middle High German masel(e), meaning "blemish, blood blister") is a highly contagious, vaccine-preventable infectious disease caused by measles virus. Other names include morbilli, rubeola, 9-day measles, red measles, and English measles.

Symptoms usually develop 10–12 days after exposure to an infected person and last 7–10 days. Initial symptoms typically include fever, often greater than 40 °C (104 °F), cough, runny nose, and inflamed eyes. Small white spots known as Koplik spots may form inside the mouth two or three days after the start of symptoms. A red, flat rash which usually starts on the face and then spreads to the rest of the body typically begins three to five days after the start of symptoms. Common complications include diarrhea (in 8% of cases), middle ear infection (7%), and pneumonia (6%). These occur in part due to measles-induced immunosuppression. Less commonly, seizures, blindness, or inflammation of the brain may occur.

Mud (from Middle Low German mudde, mod(de) 'thick mud', or Middle Dutch) is loam, silt or clay mixed with water. Mud is usually formed after rainfall or near water sources. Ancient mud deposits hardened over geological time to form sedimentary rock such as shale or mudstone (generally called lutites). When geological deposits of mud are formed in estuaries, the resultant layers are termed bay muds. Mud has also been used for centuries as a construction resource for mostly houses and also used as a binder. An Old English word for it was fen, now in most dialects referring to a type of wetland.

The Rotte (Dutch pronunciation: [ˈrɔtə] ) is a river in the Rhine-Maas-delta in the Netherlands. The Rotte is the eponym of the city of Rotterdam: the city's name references a dam (Middle Dutch: dam) which local inhabitants built across the river in the 13th century CE.

Middle High German (MHG; endonym: diutsch or tiutsch; New High German: Mittelhochdeutsch [ˈmɪtl̩hoːxˌdɔʏtʃ] , shortened as Mhdt. or Mhd.) is the term for the form of High German spoken in the High Middle Ages. It is conventionally dated between 1050 and 1350, developing from Old High German (OHG) into Early New High German (ENHG). High German is defined as those varieties of German which were affected by the Second Sound Shift; the Middle Low German (MLG) and Middle Dutch languages spoken to the North and North West, which did not participate in this sound change, are not part of MHG.

While there is no standard MHG, the prestige of the Hohenstaufen court gave rise in the late 12th century to a supra-regional literary language (mittelhochdeutsche Dichtersprache) based on Swabian, an Alemannic dialect. This historical interpretation is complicated by the tendency of modern editions of MHG texts to use normalised spellings based on this variety (usually called "Classical MHG"), which make the written language appear more consistent than it actually is in the manuscripts. Scholars are uncertain as to whether the literary language reflected a supra-regional spoken language of the courts.

Saturday is the day of the week between Friday and Sunday. No later than the 2nd century, the Romans named Saturday diēs Sāturnī ("Saturn's Day") for the god Saturn. His planet, Saturn, controlled the first hour of that day, according to Vettius Valens. The day's name was introduced into West Germanic languages, and is recorded in the Low German languages such as Middle Low German satersdach, saterdach, Middle Dutch saterdag (Modern Dutch zaterdag), and Old English Sæternesdæġ, Sæterndæġ or Sæterdæġ.
