In natural language there exists a type of sentence called conditionals. They are characterized in English by the use of connectors. These connectors can be different but fulfil, in most cases, at least two conditions: they link two sentences and they contain the word 'if'. The semantic developed to treat this type of sentences is generally a non-classical one and its most famous representative is intensional logic. The purpose of this paper is to explore the different types of conditional sentences by viewing syntactical and philosophical considerations. The existence of several kinds of conditional sentences is recognized in the current literature but the consequences are not sufficiently shown. We will investigate here the criteria which allow such a division and illustrate these differences by numerous examples from natural language. This work is not properly technical. It belongs rather to the field of philosophical logic, like the first papers published about conditional logic. To develop it in a real mathematical form would need a lot of work. The logical and semantic framework is at best outlined, because we based our analysis primarily on what corresponds to the facts regarding the logic of natural language: the examples of conditional sentences that we employ in everyday life. Nevertheless, a theory is judged by its correspondence to the facts and our approach tries to fulfil this request first. A more technical development will be possible afterwards.
