Conjunction, from the Latin coniunctĭo, is a meeting or union. Specifically, this Latin word is made up of three clearly delimited parts: the prefix "con-", which is synonymous with "completely"; the word "iugum", which is equivalent to "yoke", and finally the suffix "-ción", which can be translated as "action and effect".

Intimate, from Latin intĭmus, is what pertains or is related to intimacy. This concept refers to the abstract zone that an individual reserves for a limited group of people, such as his family and friends. Although intimacy has no precise limits, it can be said that all the acts and feelings that are desired to be kept out of public reach enter there.

If we read the dictionary of the Royal Spanish Academy (RAE), we will find that the development is linked to the action of developing or the consequences of this action. It is necessary, therefore, to trace the meaning of the verb to develop: it is about increasing, enlarging, extending, expanding or increasing some characteristic of something physical (concrete) or intellectual (abstract).
