A more thorough explanation:

A senior user is the first person to use a trademark. This person is usually considered the owner of the trademark. This is different from a junior user, who uses the trademark after the senior user.

For example, if someone starts a business and creates a logo for it, they are the senior user of that logo. If another business starts using a similar logo later, they are the junior user.

Sensitivity training is a type of training for managers and employees to learn how to treat others with respect, especially women and minorities, in the workplace. The goal is to prevent discrimination and create a more inclusive work environment.

For example, a company might hold a sensitivity training session to teach employees about different cultures and how to avoid making offensive comments or actions towards people from those cultures.

Sensus is a Latin word that means sense, meaning, or signification. It is often used in phrases like "malo sensu" (an evil sense), "mitiori sensu" (in a milder sense), and "sensu honesto" (in an honest sense).

For example, if someone says something that could be interpreted in a negative way, they might clarify their meaning by saying "sensu honesto" to indicate that they meant it in an honest or positive way.
