The connotation of this word depends very much on the context. In the case of a train, etju’het nenvy mi’ikeda ‘sidekhir kelin’han kali is not positive. It means that the train gradually reached Cologne (given that all movement is gradual, this is just one step above calling the train ‘sama, ie slow). However, if it is used to describe the action of someone, it can have the connotation of carefulness, which is something good. It is also used to refer to the slow and inexperienced way of someone learning a skill doing it.
Example: Xe’ikeda ‘dimil rejistaniha. (1S-ikeda (INF)write rejistanian. I slowly/gradually write in rejistanian)
