Je was op zoek naar: it would not be until the1980s (Engels - Wels)

it would not
ni fyddai

it would not be the only choice
nid dyna fyddai'r unig ddewis

that would not be until well into the next decade
ni fyddai'n rhaid penderfynu ar hynny tan ganol y degawd nesaf

therefore , it would not take effect until may 2011
gan hynny , ni fyddai mewn grym tan fis mai 2011

that would not be fair
ni fyddai hynny'n deg

that would not be appropriate
ni fyddai hynny'n briodol

it would not be appropriate for me to comment on the issues raised until then
ni fyddai'n briodol imi roi sylw ar y materion a godir hyd hynny

it would not be fair if we did not record that
ni fyddai'n deg pe na baem yn cofnodi hynny

i had hoped that it would not
yr oeddwn wedi gobeithio na fyddai ei angen

i would not be happy , david
ni fyddwn i yn hapus , david

we decided that that would not be wise
penderfynwyd na fyddai hynny'n ddoeth

peter law : oh no , it would not
peter law : o na , ni fyddai

changing all the trustees would not be wise
annoeth fyddai newid yr holl ymddiriedolwyr

` tapering of subsidies would not be applied
` ni fyddid yn meinhau cymorthdaliadau

it would not be about a proposition regarding enhanced legislative powers
ni fyddai a wnelo dim â chynnig i wella pwerau deddfu

edwina hart : it would not be appropriate for me to comment on that
edwina hart : ni fyddai'n briodol imi wneud sylw ar hynny

however , that would not be where it involved --
fodd bynnag , ni fyddai hynny'n digwydd lle yr oedd yn cynnwys --

he was told that it would not be possible to advise him until may on whether the scheme would run in this coming year
dywedwyd wrtho na fyddai'n bosibl ei gynghori tan fis mai o ran pa un a fyddai'r cynllun yn parhau yn y flwyddyn i ddod

if that did not happen , it would not be a complete review of the situation
pe na bai hynny'n digwydd , ni fyddai'n arolwg cyflawn o'r sefyllfa

at that point , it would not be easy for the commission to provide extra assistance
ar yr adeg honno , ni fyddai'n hawdd i'r comisiwn ddarparu cymorth ychwanegol
