With etymological root in Latin I will repel, repelling is a verb which is used to name the action of resisting, expelling, firing or rejecting something. Specifically, it is a Latin verb that is made up of two clearly defined parts: the prefix “re-”, which means “again” or “backwards”, and the verb “pellere”, which is synonymous with “push”.
For instance: “A Ukrainian soldier died when repelling the attack of the Russian troops on a base in his country”, “The security forces must be trained to repel attacks without committing crimes”, “In my country, it is common to wear red bracelets to repel bad vibes”.
The idea of repelling is used when someone must fend of a attack and get the attacker withdraw or stop their offense. Suppose that, in a city, a group of protesters marches to protest before the Legislature. Upon reaching the building, they begin to throw stones. The police who are in charge of protecting the compound make the decision to advance on the protesters to repel the attack, distancing them from the Legislature and arresting those who continue to throw stones.
Within the technological field, the verb that occupies us now is used in the same way. Thus, for example, it is common for new smart mobile phones to be presented on the market with the distinction that they have the ability to repel water. A clear example of this is the Samsung Galaxy S7, which achieves that goal because it has been equipped with devices such as a plastic seal in the area of the charging ports, a protective screen for headphones or a seal for the headphone jack.
Repel can also be about refute something or from react before something that causes rejection or abhorrence: “Have no doubts: they will always repel me that type of actions that are disastrous for our people”, “There are certain circumstances that must be repelled”.
The product that is used for repel insects receives the name repellent. In general, these are substances with some type of chemical that keeps animals away and, in this way, protects the person who uses the repellent against possible bites: “To go to the park, you will need a repellent that keeps mosquitoes away”.
As a general rule, these repellants act against insects and especially on some species such as mosquitoes, which cause really annoying bites. However, it is also interesting to know that there are many people in the world who, in order to achieve the same objective, what they do is resort to natural products that act as repellants. Which? Basil, tea tree, lavender, bay leaf, or scent keys are considered to be especially effective.
In colloquial language, the term repellent is also used with another meaning. Specifically, it is used to refer to that person who is impertinent because he wants to interfere in all matters and because he does not stop showing that he knows everything.
