Roedd 'Cymraeg 2050' yn disodli 'Iaith fyw: iaith byw', strategaeth y Gymraeg Llywodraeth Cymru rhwng Ebrill 2012 a diwedd Mawrth 2017. Wrth i swyddogion fireinio a pharatoi 'Cymraeg 2050', cafodd'Iaith fyw: iaith byw' ei hymestyn am 3 mis ychwanegol hyd at Orffennaf 2017. Mae’r cyfnod a gwmpesir gan yr adroddiad hwn felly’n cynnwys 3 mis o weithredu o dan y strategaeth flaenorol honno.
Cymraeg 2050replaced 'A living language: a language for living', the Welsh Government’s strategy for the Welsh language between April 2012 and the end of March 2017. As we fine-tuned and prepared 'Cymraeg 2050' for publication, 'A living language: a language for living' was extended for an additional 3 months until July 2017. The period encompassed by this report therefore includes 3 months of activity under the previous strategy.
