Why do some Hindu sannyāsi names end in 'ānanda' e.g., Vivekānanda, Śivānanda, Chinmayānanda etc.?
Is it a mere coincidence or is there a rule or custom?
It has nothing to do with a SannyAsi.. These names are called the DikshA NAmas or the Guru given names.
First, anyone will have the Janma NAma or the birth name, which was given by the parents.. Now, it is said that a second birth occurs for the Shishya or disciple after the DikshA (initiation) occurs.
So, to mark that occasion, it's a tradition of the Guru giving the disciple a new name.
Now, the suffixes like "Ananda" etc vary with the ParamaparA or the lineage or tradition that the disciple is initiated into..
For example, one who is being initiated into the Sri VidyA tradition, will have that name ending with "Ananda NAtha".
I will be quoting here from the book called "Nityotsava", which is considered as the most authoritative treatise on Sri VidyA rituals or even generally.
It was composed by UmAnanda NAtha (again a Guru given name for him). He was the disciple of one of the most well known Sri VidyA devotee called BhAskAra RAya. BhAskAra RAya also had a Guru given name viz- BhAsurAnanda NAtha.
How does the Guru determine/choose the name?
The process is mentioned in the following passage.
Evam idam dikshAtrayam nirvartya pashchAt tasmai ishtam mantram dadyAt |

From Nityotsava's 2nd chapter, called DikshA Krama's sub-section called IshtamantradAnam.
The points relevant for our purpose are marked in the above in bold.. But the full translation of the above passage, which is a description of how the initiation ceremony ends, is as follows:
In this manner the Guru should complete the three initiations and give the disciple his Ishta Mantra. Thereafter, the Guru, placing his foot on the disciple's head, shall instruct him with all the related Anga Mantras either during that time itself or later, in succession. Now, the Guru should make the disciple touch one of his limbs. Noting the MatrikA akshara (one of the 50 Sanskrit alphabets-a to Ksha), NyAsa of which is done during MatrikAnyAsa, on that particular limb (part of the body) touched, the Guru shall frame a name starting with that alphabet, comprised of two, three or four alphabets. And, upon adding the the suffix "Ananda NAtha" to the name thus obtained, he thus gives the disciple a new name. Thereafter, he instructs the disciple with the conducts that are described in ParashurAma Kalpasutara's 10th chapter.

So, we know that on the left knee, for example, the Sanskrit alphabet Da (द), is to be Nyasa-ed with. So, assume the disciple touches the Guru's left knee.
Then the Guru has to frame a name starting with Da, comprised of two, three or four alphabets. Let's assume the chosen name is "DayA". So, the DikshA NAma or Guru given name for that disciple will be DayAnanda NAtha.
As, already said above, the suffixes like Ananda, Ananda NAtha etc vary with lineages..
For example, a disciple who's initiated into the GAnapatya sect will have names like "Vijaya+SiddhAchArya, Sujaya+SiddhAchArya ..".. So, for that ParamparA the suffix is SiddhAchArya.
For SwAmi VivekAnanda's lineage it must be Ananda.. But, i do not know what lineage he belonged to. Anyways, his Janma NAma was Narendra NAtha Dutta.
NOTE: I have used the Sri VidyA example simply to explain the process by which the Guru gives the disciples the names.
SwAmi VivekAnanda must have got that name during his SannyAsa DikshA. And, the process must have been the same for him.
And, these suffixes like "Ananda" (for VivekAnanda's SannyAsa lineage), Ananda NAtha (for SrividyA), SiddhAchArya (for GAnaptya) depend on the Ougha-s of that ParamparA- the Divyougha, Siddhaugha and MAnavaugha Guru ParamparAs. So, it depends on that lineages original Guru's name.
Therefore, what i have proved with this answer is that it is not just a coincidence, it is a tradition.
Well, I would think that's because of the concept of Sat-Chit-Anand. It says that the truths we experience are results of Maya, and the eternal, unchangeable truth behind it is Sat. When a yogi discovers Sat, He goes into a state of Chit and is filled with eternal happiness, Anand.
So, the Anand suffix might be to signify 'Yeah, this guy has discovered Sat and is filled with Anand'
Sory, but I can't think of any citations.
