The term silt, which derives from the Latin caenum, refers to the soft consistency of mud that is found in humid places and on the beds of lagoons and rivers. It is known as mud, on the other hand, the combination of water and land.
Beyond the common use of ideas such as silt, mud, mud and mud as synonyms, silt refers specifically to the mud found in the subsoil or at the bottom of some body of water. In those cases, the soil is often mixed with the groundwater.
For example: “The little boy was jumping for hours in the mud, having fun”, “Be careful not to slip through the mud”, “The boat got stuck in the mud while the young people tried to cross the pond. “
Due to its consistency, when a large amount of silt accumulates it can be difficult to advance on it. A person who sinks his feet into the mud in this way may slip or have to exert great effort to lift his feet and take steps. If the water level is low in a river or lagoon, it is also possible that a boat is stranded due to silt.
There is a particular type of slime known by the name of lama, which is not used in everyday speech. It is specifically the silt that remains at the bottom of places where there has been water for a long time. Its composition is not the same in all places, since it depends on the parts through which the currents have passed and the type of earth they have washed.
In general, this class of silt is a compound of the following materials: humus (or mulch), clay, calcareous earth and remains of animals and plants. Large rivers have large banks at their mouths into the sea, which extend considerably; in Egypt, to cite one case, the fertility of the soils is due in large part to the banks of the Nile.
The fertility is one of the fundamental points of the lama, because it is a very effective type of fertilizer, especially if you have a high content of plant remains. At the bottom of lagoons or ponds where aquatic plants grow, on the other hand, a silt forms that cannot really be used for this purpose unless it is left in the open for a minimum of two years.
Something similar happens with sea silt or silt, which can only be used as compost if it is left to rest for a couple of years. Silt is defined as a sediment transported by the wind and rivers in suspension, until it is deposited at the bottom of water courses or on surfaces that have been flooded.
Taking up the example of the Nile River, it was common for this combination of matter to be deposited in dry areas after floods, where it formed an excellent compost that was ideal for agriculture in ancient times; however, after the construction of the Aswan Dam, the silt flow was interrupted.
The concept of slime, on the other hand, can be used symbolically to name what is dirty, unpleasant, rugged or unseemly: “I was thrown in the mud because of alcohol, but I managed to get out thanks to the support of my family”, “To develop a political career you have to put your legs in the mud and I am not willing to do it”, “The mud of corruption splashes all the managers of the company. “
