If your written English had been half of your trolling mettle, it would be much less cumbersome to interpret your sentences. “We have developed worlds third largest Solid Rocket Booster.” is as correct English as it would be to assume that you live holed up in an apartment block, fapping to gay **** and dressing in panties. Use a goddamn prefix, the appropriate one in this case being the article ‘the’. Note the difference in the following two sentences:
“We have ‘the’ developed worlds third largest Solid Rocket Booster.”
“We have developed ‘the’ worlds third largest Solid Rocket Booster.”
Does your insolence note the difference which the placement of the prefix makes to the meaning of the overall sentence, or is proper English too advanced to incorporate with the Indian-English they teach you in Bihar. In addition to being an affront to basic sentence construction, and therefore being vague and partially unintelligible, you’ve failed to use an apostrophe in ‘world’s’ and have poorly decided that solid rocket booster is a proper noun and therefore the first letter should be capitalized.
The correct sentence, taking from the clarification you made where you’ve rightfully denied claiming India is a developed country, should read, “We have developed the world’s third largest solid-fuel rocket booster.”
The reason you have to put up with this simple lesson in grammar here on PDF, now, is because you either slept through Grade 5 (assuming you have a formal education) or have utter disregard for the amount of sense your posts make. I am willing to accept it’s the latter because judging from your other posts you diligently mesh together generalized copypasta in a seemingly successful attempt to (i) respond for the sake of responding; (ii) come off as a defender of India on PDF; and (iii) get Thanks for your profile, all three of which you do with impunity and without regard for sense. To add insult to injury, you are also getting schooled in English because you add emoticons to your posts, to enhance emphasis because in the absence of that emoticon your command of English does not allow you to effectively assert your proposition. Read a book, goddamn it!
