Rô has an inherent vowel in it, which is ô, as in most other Assamese consonants. But, many a times, ô is to be replaced by another vowel or swôrôbôrnô. In such a case, the vowels change their forms.
As examples:
ৰ + আ = ৰা
ৰ + ই = ৰি
ৰ + ঈ = ৰী
ৰ + উ = ৰু
ৰ + ঊ = ৰূ
ৰ + ঋ = ৰৃ
ৰ + এ = ৰে
ৰ + ঐ = ৰৈ
ৰ + ও = ৰো
ৰ + ঔ = ৰৌ
Words starting with ৰ
Given below are examples of words starting with ৰ.
When ৰ is added before another consonant to form a conjunct, ৰ turns into reph. In other words, reph indicates that there is a r sound before the letter it is used before.[4]
For example:
ৰ + ক = ৰ্ক
ৰ + খ = ৰ্খ
ৰ + ঘ = ৰ্ঘ
ৰ + ছ = ৰ্ছ
ৰ + জ = ৰ্জ
ৰ + প = ৰ্প
ৰ + ম = ৰ্ম
ৰ + য = ৰ্য etc.
Examples of words are[3]আৰ্জন (arzon, which means 'gain'), কৰ্তা (korta, which means 'doer') etc.
Rô-kar (ৰ-কাৰ)
When ৰ is added after another consonant, ৰ changes into rô-kar. In other words, rô-kar after a consonant means that there is a rô sound after it.[5]
For example:
ব + ৰ = ব্ৰ
প + ৰ = প্ৰ
স + ৰ = স্ৰ
ল + ৰ = ল্ৰ
শ + ৰ = শ্ৰ etc.
Some consonants change their shape when rô-kar is added.[5]
For example:
ক + ৰ = ক্ৰ
ভ + ৰ = ভ্ৰ
ত + ৰ = ত্ৰ
