Samas (compound words)

Samas is the grammatical process by which two or more meaningful words are compressed into a compound, while vigrah expands that compound to show the hidden relationship between its parts. In this process, case markers, postpositions, connectives or explanatory words are dropped or suppressed, and the resulting compound is called the samast pad. The explanatory expansion that opens the compound back into its relationship is called vigrah. According to the RPSC Sub Inspector/Platoon Commander Paper One Hindi syllabus, this paper carries 200 maximum marks. For exam recognition, do not begin with a memorised label. Begin with the question: what relationship is hidden between the parts? In rajaputra, the hidden relation is raja ka putra; in yuddhabhumi, it is yuddh ki bhumi; in nilkamal, it is nila kamal. The compound word is shorter, but the vigrah shows the full sense.

Three terms must be kept separate. A samasik pad is the compound expression being studied. Samast pad is the compact final compound after combination, such as gramavas, dinrat, dashamukh or chandramouli. Vigrah is the unpacked meaning: gram mein vas, din aur rat, das mukh wala, chandra ko mouli par dharan karne wala. In many school grammars, samasik pad and samast pad are used close to each other, but in solving questions the safer habit is this: identify the given compact word, mentally expand it, and then classify the relationship shown by that expansion.

A true samas normally has two tests. First, its components must be meaningful units, not merely sounds created by phonetic joining. Second, its expansion must show a grammatical or semantic relation between those units. Devalaya can be expanded as dev ke liye alaya, so it is sampradan tatpurush. Vidyalaya can be expanded as vidya ke liye alaya, so it is also sampradan tatpurush. But if a word is only a phonetic change of adjacent sounds, the issue may be sandhi rather than samas. Ram plus Ishwar becoming Rameshwar involves a sound change at the boundary; the resulting word may be explained semantically too, but the immediate recognition question may be testing sandhi if it asks for sound combination.

For RPSC-style objective questions, the exam usually gives one word or a set of options and asks which has a given samas, which does not, or what type is present. The operational method is fixed. Split the word into likely parts; write the simplest vigrah; mark the hidden relation; then choose the samas type. If the vigrah needs ka, ki or ke, expect sambandh tatpurush. If it needs mein or par, expect adhikaran tatpurush. If the first member describes the second directly, expect karmadharaya. If the whole compound points to a third person or object not named directly, expect bahuvrihi. This method prevents the common mistake of choosing a type by the visible shape of the word alone.

A non-samas option often looks tempting because it is a familiar joined word. Check whether it actually has two independent meaningful members. Words formed by prefix or suffix, such as anushasan, naitikta or manavta, may be word-formation items but not necessarily samas. Likewise, some lexical words are not to be forced into a compound analysis unless their parts and vigrah are clear in standard grammar. The exam rewards disciplined recognition, not over-analysis. A strong answer is therefore not that the word sounds compound-like; it is that the word expands into a specific relation, so that samas type follows.
