"मेरा बेटा लंबा है।"

Translation: My son is tall.

[Shivaadh]

What does the dot above the l signify? Is it a vowel?

[vinay92]

The dot indicates that you have to add a nasal consonant there. This nasal has to be pronounced with the same place of articulation as the consonant after it. So, लंबा is pronounced 'lambaa' and may also be written as लम्बा.

Similarly, हिंदी is pronounced 'hindi' and may also be written as हिन्दी.
