The SIL Open Font License (OFL) is a free, libre and open source license specifically designed for fonts and related software based on our experience in font design and linguistic software engineering.
The Open Font License is a free software license, and as such permits the fonts to be used, modified, and distributed freely (so long as the resulting fonts remain under the Open Font License). However, the copyright holder may declare the font's name as being a "Reserved Font Name", which modified versions then cannot bear (this includes subsetting for web fonts). The License permits covered fonts to be freely embedded in documents under any terms, but it requires that fonts be packaged with software if they are sold. Open-source fonts are a popular choice among designers. Most open-source fonts utilize the Open Font License (or OFL) by SIL international. The only stipulation is that anyone cannot charge others to use them.
Does the SIL Open Font License v1.10 mean I can use this font commercially?
You can use it for setting type in commercial promotions and products, and you’re also allowed to re-distribute it for that reason. You can even re-distribute it freely (as long as you mention its source) when necessary.
But you’re not allowed to ask money for the font itself !. Follow quora
We also recognize the need for people who are not familiar with English to be able to understand the OFL and this FAQ better - in their own language. If you are an experienced translator, you are very welcome to help by translating the OFL and its FAQ so that designers and users in your language community can understand the license better. But only the original English version of the license has legal value and has been approved by the community. Translations do not count as legal substitutes and should only serve as a way to explain the original license. SIL - as the author and steward of the license for the community at large - does not approve any translation of the OFL as legally valid because even small translation ambiguities could be abused and create problems.
We give permission to publish unofficial translations into other languages provided that they comply with the following guidelines:
1) Put the following disclaimer in both English and the target language stating clearly that the translation is unofficial:
"This is an unofficial translation of the SIL Open Font License into $language. It was not published by SIL International, and does not legally state the distribution terms for fonts that use the OFL. A release under the OFL is only valid when using the original English text.
However, we recognize that this unofficial translation will help users and designers not familiar with English to understand the SIL OFL better and make it easier to use and release font families under this collaborative font design model. We encourage designers who consider releasing their creation under the OFL to read the FAQ in their own language if it is available.
Please go to https://scripts.sil.org/OFL for the official version of the license and the accompanying FAQ."
2) Keep your unofficial translation current and update it at our request if needed, for example, if there is any ambiguity which could lead to confusion.
If you start such a unofficial translation effort of the OFL and its accompanying FAQ please let us know, thank you.
