Problem: The Sumerian language is generally regarded as a language isolate in linguistics because it belongs to no known language family; Akkadian, by contrast, belongs to the Semitic branch of the Afroasiatic languages. There have been many failed attempts to connect Sumerian to other language groups. It is an agglutinative language; in other words, morphemes ("units of meaning") are added together to create words, unlike analytic languages where morphemes are purely added together to create sentences. Some authors have proposed that there may be evidence of a sub-stratum or add-stratum language for geographic features and various crafts and agricultural activities, called variously Proto-Euphratean or Proto Tigrean, but this is disputed by others.
What are morphemes?
The answer is the following: "units of meaning"

Problem: During World War II, detailed invasion plans were drawn up by the Germans, but Switzerland was never attacked. Switzerland was able to remain independent through a combination of military deterrence, concessions to Germany, and good fortune as larger events during the war delayed an invasion. Under General Henri Guisan central command, a general mobilisation of the armed forces was ordered. The Swiss military strategy was changed from one of static defence at the borders to protect the economic heartland, to one of organised long-term attrition and withdrawal to strong, well-stockpiled positions high in the Alps known as the Reduit. Switzerland was an important base for espionage by both sides in the conflict and often mediated communications between the Axis and Allied powers.
What was the original goal of the Swiss military strategy?
The answer is the following:
protect the economic heartland
